So! Here's what I've done. Since Texas is unlikely to be a major player in this, I'm going to say her colors are Steel/Steel, since that is the standard Halo "black" and it's what Roosterteeth went with until they started using their live-action animation. This way, Revan, you can have Black/Black as your color combination and we still stay true to Tex's "black" armor in the series.
