I am trying to try for ceruleam blue
72 red, 80 green, 95 blue is ceruleam blue
-216 red, 175 green, 80 blue is original color
which equals
-144 red, -95 green, 15 blue

I will be using 24 deepen blue, 8 lighten green, and 3 lighten blue
that should give me -144 red, -96 green, and + 18 blue, if they do have a value of 6 each
so i'll see how it goes
though I currently have seeds in my garden so cannot these until they are picked
