Yellow Violet may be your next best color for catching Crappie. LOL I make a white shad with the violet highlights that works good around here! I heat 30 seconds at a time and stir every time until it turns clear then i start 15 sec until i reach 350 F. Yes u can add a dark color also Chartreuse will work don't know how much violet u have in there might try little see what it looks like before u do the whole batch.
