A question of color

[raymondsmindjob]

Stuck here and need some feedback or advice, please.

Working on this project and I decided to cover the visible side of myeggcrate false bottom with great stuff.
Then I painted and sealed it, but I'm not sure I like the color I used?
The rest of the background is brown, but I really feel like I don't want the whole project to just be brown, Its in a 65 gallon and thats a lot of brown.
On the other hand, brown would make the project look more uniform.
I also have the following colors available: black, white, green, blue,red, and terra cotta.
Right now it is painted beige?
Attached is a pic of my false bottom painted as it is now, and also a pic of background. Want to make my tank look as natural as possible.

Please respond
