sapperastro Posted August 21, 2020 Share Posted August 21, 2020 We have Xtracolor here in Aus? I remember they were being imported years ago, and then vanished. Same with the Xtracrylix. Who is getting them these days? Link to comment Share on other sites More sharing options...
Michael louey Posted August 22, 2020 Share Posted August 22, 2020 Hi Sapperastro,  The only 2 stores I recall in Melbourne that had xtracolour were Snowy Mountain Models and Showcase models, both sadly closed now.  I've heard there was an outer suburbs place that had some old stock but can't recall its name.  Cheers  Michael Link to comment Share on other sites More sharing options...
Casey Posted July 29, 2022 Share Posted July 29, 2022 (edited) Hello. I am practicing bit of (on purpose) necromancy here, but this color seems to be quite elusive for acrylics users. Â Here is the best result I've achieved so far using acrylic paints: Â Â I've achieved this by matching the color to the original spectral curve. Â Purely in math there is an theoretical recipe using Golden Fluid Acrylics, in MASS parts: Â Â I've mixed it and added 40% (mass) of Ultra Matte Medium from Liquitex to the mixture to get the same level of matt as original paint.

Thank you!  It is my scientific way to find out a best mix of professional range acrylics:  https://goldenpaints.com/products/colors/fluid  I am going to definitely use this recipe for my next Azure blue spitfire.  I can't believe this thread is more than 12 years old... that shows how strongly people can feel about a shade of blue And I thought I was color-crazy.

John Posted July 30, 2022 Author Share Posted July 30, 2022 Coincidentally I've been thinking about this myself. I was busy throwing some of Precision Paints excellent Azure Blue at my P-40 build in the Revellogram GB when I started to wonder if the situation for our acrylic brethren had improved any since the last time we looked at it. Us enamel users are well served now with 3, or at least 2 and a half given that Humbrol have withdrawn 157, good matches. 157 isn't that difficult to find though.  In the spirit of enquiry I ordered 4 acrylic paints that weren't available the last time I looked. They are :   plus Humbrol acrylic 157 in a dropper bottle, which hasn't arrived yet. I'll post the brush outs shortly but one thing I can say straight away is that the 2 AK colours aren't the same...  Humbrol 157 should be spot on, shouldn't it...?  John   4 1 Link to comment Share on other sites More sharing options...

Â Also the paint finish is something a lot of modellers do change on the fly.. You know, gloss varnish at everything, decals and weathering, then maybe matt varnish... if you do it that way the paint finish you start with is more a liability than asset...

Scott Hemsley Posted July 30, 2022 Share Posted July 30, 2022 (edited) John.... in my experience, never brush out AK colours with the goal to compare them to a colour chip ... airbrush them! You'll find the results quite different and much closer to what is advertised. Unfortunately, I've found that they're only one of the paint mfgrs I've tried over the years that I've been modelling (some 55+) that have a problem with colour matching of their paints ... brushed vs sprayed. Maybe I should try 'lightening' them and matching to the adjacent sprayed portions, prior to any touch-up work up with a brush?  Case in point, I've a jar of RAF Ocean Grey (RC288). In the jar, it looks to my eye, more like Dark Sea Grey or 'seaweed green' as I sometimes refer to it. It brushed out like that to the point where I thought I got a mislabelled jar. Upon spraying it onto a paint mule, my opinion of the AK Ocean Grey changed dramatically. At this point in time, it's the best flat RAF Ocean Grey I've come across (your opinion and that of the colour police, may vary). Either way, it just looks right to me   To a lesser extent, I've made a similar discovery with their RAF Dark Green (RC286). Some may claim the brushed colour is much closer to the RAFM chip that many here are familiar with, but when brushed ... it is decidedly darker than the sprayed version. I've a RFI that features a Sabre Mk.6 here on BM (A look back - A tail of two Swords - Ready for Inspection - Aircraft - Britmodeller.com). If you look on the extreme front of the port side nose of the Mk.6, you'll see where I had to touch up the Dark Green with a brush after I finished decaling, so spraying wasn't an option.  Moral of story? I now withhold judgement of my AK paints until I test them out with the airbrush because what it looks like in the jar (or how it brushes) isn't necessarily how it dries when sprayed.  Scott  BTW, since we're discussing colour, the Sabre 5 is Model Master's RAF Dark Green and Compucolour (old but still perfectly good) or Model Master's Extra Dark Sea Grey - I forget which with AeroMaster PRU undersides. The Sabre 6 is done up in AK's RAF Dark Green, Compucolour (old but still perfectly good) or Model Master's Extra Dark Sea Grey - I forget which and Model Master PRU Blue.

Casey Posted July 31, 2022 Share Posted July 31, 2022 2 hours ago, John said: presumably they use the same information My biggest fear is they may use "Make the cheapest recipe possible that is still somewhat similar color" as their matching criteria... For large scale production, this is probably what I'd use... Â This is the problem of commercial hobby paints, the bigger they are, the more incentive there is to cut this 5 cents per bottle of 'unnecesary' violet pigment from recipe. Â Mixing my own colors gives me the luxury of doing 'the best match regardless of cost'. My pigments database becomes more accurate with each real paint sample I am preparing, and it already feels good to see the predicted (simulated) results to be that close to reality. 3 Link to comment Share on other sites More sharing options...
John Posted July 31, 2022 Author Share Posted July 31, 2022 I don't think manufacturers are necessarily skimping. The matching criteria over the years seems to be what I've come to call "The Tyranny of FS595", the assumption that every colour can be matched to a FS595 equivalent and the part of the operation doing the actual manufacturing, in house or an external contractor, are given the FS595 reference and are asked to match it, which they do. A lot of the time that's good enough of course, but there are also examples of where it doesn't work and MAP Azure Blue is a case in point, especially since manufacturers who understood what they were trying to match achieved it with commendable accuracy. John  5 Link to comment Share on other sites More sharing options...

JackG Posted August 1, 2022 Share Posted August 1, 2022 Many hobby paint brands will add an FS number to their label, perhaps because the system is so popular with modelers.  Don't think that it necessarily means that that is what their formula was matched to.  According to Nick Millman's studies, no FS value is a good match to Azure.  35231 is too dark with a measured difference of 7.80, while 35240, though closer at 5.43, is still too dark.   regards, Jack 1 Link to comment Share on other sites More sharing options...
John Posted August 1, 2022 Author Share Posted August 1, 2022 Lifecolor UA 098 is pretty much a perfect match for 35231 so I've no reason to doubt that's what they were aiming for. They did a good job too.  I've still to check Mission Models against FS595.  John Link to comment Share on other sites More sharing options...

Fingers crossed. Steve. I am also really excited about the extra large "Made in the UK" sign and "Gen 2". I so wish they removed old *autocensored* stock and just replaced it with the new formulas, since now there is no way to even select that option it in their shop.

Jamie @ Sovereign Hobbies Posted August 2, 2022 Share Posted August 2, 2022 18 hours ago, John said: However FS595 matches aren't unusual:  At the risk of sounding sour or cynical, that's because it's cheap and easy. Most commercial paint tinting machines and software packages are either supplied with, or offer as relatively inexpensive extras, FS595 tinting formulae.  It's still possible to get that wrong, because different brands of commercial pigment tints are slightly different - and there are examples of (mostly Spanish and Italian brands) who can't even get FS595 colours right, probably because of this.  Push button > something comes out > sell it  At best, just using FS595 means you can shortcut the time consuming and cumulatively expensive route of searching for better reference materials which often carry different gravitas and needs consultation with someone fluent in that language who is also clued up enough to understand the subject, yet doesn't have a non-justifiable bias themselves - all of which can be rather difficult, then going about the process of iteratively developing tinting formulae for each of the colours you wish to produce. Instead you can just ask on a forum what FS595 is closest to MAP Azure Blue and make that, or quicker and cheaper still, just browse IPMS Stockholm's website.  Ultimately, there's little advantage to getting anything correct. People will buy it simply because you tell them it's what they need. There will always be a handful of people around the fringe who actually care, but mostly we are scoffed and laughed at by the "I've no idea what right looks like but if it looks right it is right and it looks right to me" brigade. We don't really impact sales figures. If getting things wildly wrong mattered, some very successful brands would have vanished years ago. 10 1 Link to comment Share on other sites More sharing options...
