But the members that are non-holders have the same color as VPS holders. I should think to make a special color for VPS holders and for members that are non holders. Just in mine opinion.

Nope, it's different. VPS holders marked in bold while non-VPS holders marked in normal style.
Also, VPS holders have color light blue while non-VPS holders have normal blue color.

Let me take an example:
VPS holders: @tiwil
Non-VPS holders: @demon
