You have to start with a black bait. I use LC colors; I've never used Dels, it may be different. If you don't have the black background you won't get the full effect of the highlite.
If you are trying to get to what I saw in the Yammie picture, that is a laminate. You can't get there from here,lol.
The baits you showed are neat in their own right. You'll have to increase the black to really show the red.
