mixing gray scale

[huskystafford]

You're definitely onto something buying large bottles of primaries and get real close with your recipes then dial it in from there for color matching. I'm still such a noob with color mixing yet myself. Not that I've much time to work on that, let alone actually paint lately.

I was noob lucky many times before I started to make cards. I mixed bunch of diarrhoea looking colors

I think by the time you get a large part of your cards done, you will have learned mixing well enough to not generally need them.
I always thought it was a good idea though. For many reasons

I tend to run into this problem- I know I mixed a color but I can't remember how I did it. These little reference cards would be an awesome way to remember what I did. Now I just have to find where I put the cards! Lol
