It's easy: You don't like it so don't do it. I don't like bargellos so I won't ever make one. With all the different patterns and fabrics out there, the options are huge. I wouldn't spend precious time on something that doesn't give me joy. Now that said, I have started projects and found out that I didn't like it much after I started. Sometimes I passed the project on to someone else and sometimes I decided to finish it, just to say I did. Generally though, I have a pretty good idea what works for me and what doesn't.
As for the fabrics and colors, have you considered taking a color class? It really opened my eyes to what actually goes together and what doesn't (and why).
