Okay, I think I am starting to get it. I saw your post yesterday but didn't respond (at least I don't think I did, pain meds...
But from what I am reading, and maybe reading too much into it, you are looking at this as your art, your creation. You want to create things in your style. This is why the color is bugging you so much.
Unfortunately, we create based to some degree on what the the person ordering the cake wants. THEIR requests, likes, dislikes, etc. It just doesn't work to make only the cakes that appeal to us. I think every decorator has their own style. For instance, Colette Peters, Sylvia Weinstock but even they generally work within the desires of the client.
Unless you are only going to create cakes for your pleasure and give them away you have to contend with the colors you don't like and styles etc. We all do, it's just part of the job so to speak.
I think for any artist, they have a vision but it has to meet somewhere with what other people want.
I hope all this rambling makes sense but it is the feel I am getting from your posts. Try to look at it from the workmanship and overall look. We all see the flaws and the things we don't like. Even if you hate it, every caker goes through it some time. Have a chocolate and let it go, ice cream is good this time of year too!
