Model paint comaprison, conversion and historical charts
All these model paint comparison and conversion charts use Humbrol paints as the benchmark, so if you want to convert from Heller to Vallejo then you'll have to go via Humbrol.
I have tried to be as accurate as possible but I have to point out that the conversions and the colours used in the charts are to be used as a guide only as it is impossible to be totally accurate for several reasons including differences in monitors, printers and the good old fashioned human eye! Anyway, I hope these prove useful to you.

Here you can download the online charts that companies like Humbrol and Games Workshop release. These are some of the charts that I have used to create and compile the charts above.
