Brown rhyolite?

I have this sample which corresponds to a volcanic dome. The rock appears to be a rhyolite with a porphyritic texture of plagioclase minerals, but I have never before seen a rhyolite with this matrix color.

Gravity

Hello everyone, I'm a geology student and I'm doing my thesis using gravimetry to estimate the geometry of a pluton. The problem is that during the data collection campaign, they didn't use differential GPS, so the uncertainty in the elevation data is high. Any recommendations? Similar cases?
