Special Lyre colors

I've gotten about a dozen so far(from a little more than 1 stack of bait at rank 3 fishing), no repeat colors, no pure colors, But it does seem they tend to be aesthetically pleasing ones(nothing brown, nothing dull, and nothing that resembles vomit). 3 or 4 were off-white, but the shades were slightly different on all of them.

I've gotten a few browns and "vomit greens" so....you just had good luck.
