Depends on your water clarity as to what colors are best. I know Red and White is a long time bait color, but I just do not use it. Mostly I use Chart/Blue/Chart or several other when stained water, but clear I want Silver/Silver/Blue or again a few others I like that are like that.

It also looks like you cut the tips off the marabou after it was tied? That would be a no no! Also looks like maybe you tied in the stem and all of the feather which I don't do hardly ever. I may use a stem 5 % of the time if it's so thin it wouldn't matter, but 95% of the time I take the feather off the stem and stack that until I get enough, then one cut after I have picked them up and know how much I want to tie in. I will pinch the marabou right where I want to cut it again on the same end that was attached to the stem and cut that off, but never the tips.
