White base and Color rehearsal


Air-Valve Autobot!
I don't have good eye for the grey levels on a color image , so , to paint the white base for my Ironman t-shirt , I took the image in photoshop , lower the saturation of color and print a B&W version for reference

After finishing the white base I was afraid to mistake the colors and ruin the metal effect , and in that case , I just don't have idea how to fix it (if possible)
I found very useful mix the colors and do color test on my B&W printed image before , maybe is not exactly the same , but is close enough .

That is a great ideal and I have done that a time or two (mainly on candy work) to see what is will look like and how bright I would have to leave the brights.
I think others will find this very useful
