scar/tatoo colour chart

my storm artifact was blue. i thought id waste my orange dye on it, and it turned a very true blue. My armour was red, i figure since the opposite or orange is blue, and the opposite of green is red, by using green dye, i should be able to get a red storm artifact. Instead it turned a bubblegum sort of pink. Can anyone direct me to the scar/tatoo colour chart? they both work in the same way, i assume. ^^;

I didn't see anything on Monk Tattoo color tricks, but here's a link for Necro Scar and Chaos Axe Color Charts:
