need help with first photchop

alright i just am half way fnished with my 1st photochop and i have run itno a problem. I took an intgra and added the spoiler and a front bumper and side skirt from a nsx that are all yellow and applied to my car so all my bumpers are yellow and the rest of the car is teal. Now i was trying to chang the teal by using the lasso tool then going to hue satruation and i selcet my color but when i press ok nothing happen what do i do?

after you select the bumper and side skirts (and whatever else you want to change color of) then copy it , paste it , then go to Image>Adjustements> and go with Hue/satrutation , color balance , contrast/brightness to adjust those...

to make it easier to get the proper color, after slecting the section and copy/pasting, goto desaturate then use color balance, levels, etc.

alright thanks
