I'm just back into modelling after a 2 1/2 year hiatus. I used to use the Ultimate Paint Conversion chart that was available at www.paint4models.com but it doesn't seem to be working. It was really good, but I don't know if it was being maintained. If it is now defunct, what is the best online colour conversion resource? I'm particularly keen on Humbrol to Vallejo, Humbrol to Tamiya and Humbrol to Mr Color. Thanks
