Comment 6 for bug 1844982

The problem is that the color of LAYER_VIAS_HOLES in high contrast mode depends on other layers.

Patch proposal:
-Added rule for vias in the color selector, that checks if the via does not belong to any layer registered in m_activeLayers that is visible, then apply a dark color.

Note: When toggling the visibility property of a layer a via is on, the via color does not change if that layer is the selected one. I need to select the layer name to refresh it. I don't know if this should be considered as a related bug, or a different one. See video
