H!If I make a top water lure or a jerkbait.,I like to have dark colors on the belly and flo or very visible colors on the top!!The reason is simple!,Fish that pray on top water lure see it from below,so if the belly is white it will blend with the sky!!So less visible for tha fish!And the reason for the bright top is for the fisherman!Easy to see the lure in the water.
