The gold and blue hilites are the two I use most. Violet being third. fourth and fifth are green and then red.
I think of it as pearls add color to the inside plastic of the bait, where as hilites add a "skin" of color on the outside.
I usually add a smidgeon or two to 8 oz plastic. Get a set of smidgeon, dash and pinch measuring spoons.
Here is a violet pearl with green hilite sheen that I call Mystic Pearl. Looks awesome in the sun.

This is a copy of a Mister Twister color. Very light amber with blue hilite.

I call this Purple Haze

As said. green with gold hilite makes a great bass back color.
Green pumpkin with blue HL is magic craw.
Have fun with it...Bill
