Spotted this from a recent Google search that I did.
I often find it frustrating when reading articles when the artist is using a brand of paints that I do not own. While most of the time it's possible to work out an alternative this site gives the direct equivalent is different brands.
The drop down menus of the left uses acronyms but they are straightforward to use. (eg. GW = games workshop, VGC = vallejo game colour)
No more guessing games!
