I don't know if you can get it in India but if there are auto parts stores there you can buy some 1/8 inch pin stripe tape and go around the edges of the top colors to give it a pop, it really adds to the trim. It's normal for people to add more colors to the bottom of the plane so you are able to instantly tell the top from the bottom. As Don pointed out, stripes of about 4 inches wide are about the norm. I'm not a big fan of the trim sheets, I use covering to dress up my planes then use the auto pin stripes to dress it up a bit more. One of my favorite stripes is a double stripe tape. It has one thick stripe and a thin stripe, looks great. I buy a pack or two every time I run into it. I also bought one of the GP trim stripe cutters so I can cut my own from covering. Any contrasting colors works very well. I have also discovered i like circles better then stripes but it's a lot more work. After I did a Kaos with circles on the bottom I had several guys start using them instead of the stripes.
