**help with Preloader** use image NOT bar

HELLO!!!

so i am in the midst of working on a game, and i need a preloader SHOCK :!:
i have one that works fine, it’s a pic and some text with a load bar and a % value shown. but i don’t want a ■■■■ bar, there evil!!! so i want to fill-in the white space with light green, is there an easy way to get this done?
I’ve been at it forever and i feel quite silly not being able to get this done!!

Thank you for your help,
H.C.A.
