Back in my younger days taking some art classes, they drove home the point that from a perspective of human psychology, anything bright draws the eye to it. In your case, the knee plates and radiator are now the brightest most distinctive design element on your bike, so you see those parts MORE than anything else. They're nice parts for sure, and that might be the goal of the covers. That said, if you want them to blend in more, either brighten everything else up, or darken those parts.
Where'd you source the parts? Nice quality based on your pics.
