What color frame bag would fit this green GT frame ?

Hi,

im new and need some help.
this is my first bike, i got it for really cheap and added the handlebars and new crankset + pedals.the saddle is only temporary.

1. Is this a GT Timberline? The original owner couldnt tell me and I am not 100% sure.
2. What color would go nice for any bags I might add to the handlebars / the frame?

and also please share any and all criticism or ideas you have.

Sorry for not taking a picture of the drive side.
Also sorry for the ugly fenders, I think I need them for the upcoming wet fall.

Thank you !
