Learn English – Is it “mat” or “matte” for the color around an image

synonyms

We are writing a program to add a “matte” around an image but the developers aren't sure whether to name the method matte or mat.

The Oxford American dictionary has mat as an alternative spelling of matte.

In this case, we think mat is less ambiguous because matte when referring to a color could mean either the glossiness of the color or to its purpose as a framing element.

Any advice?

Why not call it a frame or border instead?
