Making yellow less orange?

Recommended Posts

Nick Millman writes in "Real Colors" that "ANA 505 Light Yellow superseded Lemon Yellow and is approximately similar to FS 13655 (which also superseded it in March 1959). However, 505 is noticeably lighter, brighter and less 'orange' than FS 13655.

 

I have MRP-386 whuch is labeled as FS 13655 / ANA 505. I don't know if it matched to FS 13655, probably it is. Is it possible to make a yellow paint less orange by mixing it with some other colour? At some point, maybe ever for my SB2U-1, I will need Lemon Yellow, I would like there to be a noticeable contrast between the wings and the Lemon Yellow parts. I'm planning to use Mr Hobby C329/H329 for the US Navy Yellow. Maybe there is already enough contrast between these two colours. My DSPIAE colour test cards haven't arrived yet, they would be very handy for situations like this, when deciding what colours to use.

An orange looking yellow paint is no longer a primary colour.  It is has red added to which creates the warm orange like hue.   You need to add a pure yellow paint to decrease the orange.

Concur with the above.

 

To get from an orangy yellow to a lemon yellow you'd probably end up adding so much 'prime' yellow that you'd be better starting the lemon yellow from scratch.

Thank you for the replies. I am not trying to make an orange yellow a bright yellow. I have pretty 'yellowy' yellows, but i'm thinking if there is a way to make them even brighter. For instance for a civilian Tiger Moth, in photographs they look quite bright, with minimal orange tones. Most of hobby paints are for military planes, so there's very little truly pure yellows available.

Tamiya has released a yellow pigment, LP-83, which is used to make your own mixes. I should maybe get a jar and experiment with it.

If you mean lighter, just add white. But if you want more saturated, then there is a maximum chromaticity (think: saturation) for each pigment that you cant go beyond since it is physical property of that pigment itself.

Millman writes that Lemon Yellow was at the same time lighter and brigher than fs 13655. Would it be pointless to add both white and yellow pigment - Tamiya lp-83 - to a yellow paint, would they just negate each other?

I can only assume he meant less saturated (lighter) and brighter (reflecting more light). In this case adding white to more saturated (stronger) and darker yellow could do the trick, but you still need to be mindful of color hue which I assume was the same as of FS13655. Hue shifts also happen when adding white, with saturated 'orangish' yellow you can expect hue to shift towards green more than it would suggest when drawing a straight line from yellow to white in a color space (the resulting color gradient is almost always a curve)

 

FS13655 is a very saturated color.

Yellow my fav color ! Just ask Casey how many times I have asked her  xD

 

@TheKinksFan Get Liguitex fluid Med Cadmium Yellow or even Primary Yellow for more lemony Yellow.  It's as yellow and saturated as it will ever get in a paint!

 

I am Super happy with them ...

 

Speaking of Liguitex, @Casey if  able  would you please publish their measurements converted to  D65 2 Degree (SRGB)  preferably in a thread?

 

 

I think it would be very useful to have  and they would be super helpful.

 

Its my new favorite paint and I intend to use them a lot

Another idea is to use a white primer underneath the yellow you want to come across as brighter.  Something else to consider and try in your paint tests is the sheen of the paint in relation to a different sheen beside it.

Thanks for the suggestion, that Liquitex stuff really is a lovely yellow. But I don't airbrush water-based paint, so I'll have test Tamiya's lacquer pigment.

That's what I usually do, yellow doesn't cover properly - at least MRP- even aluminium or silver. I was lazy and didn't put a white base on a 1/72 life raft, and it took ages to get some kind of coverage.
