thank you TD4438. the color is actually Tamiya's Lemon Yellow.
the first try was actually just Yellow, but for some odd reason, the paint looked like it was paintbrushed. so i completely removed the pain, resanded, reprimed, resanded and repainted.
what bothers me is that you can clearly see the "orange peel" on the paint. and since it's Lemon Yellow, we should actually say "lemon peel" !
