As a base, acid stains are well known, tried and tested. But watch out for putting too much stain into the concrete pores. You have to leave room for the topcoat to anchor itself! Select a thin-coat polyurea to avoid the possibility of out-gassing that comes with high viscosity topcoats. (Those micro-bubbles would give you an foggy, “frosty” look.) Another option would be a metallic epoxy floor. Artistically, this has the advantage that if you don’t like the way the appearance is starting to look, you can easily roll over the wet epoxy and try a do-over. Or go wild and make the colors crazy and mute them down by coating them with a semi- transparent (almost clear) metallic epoxy. On a trial board, of course!!

Or a 2-component, UV-stable, polyaspartic aliphatic polyurea that can be applied in thicker films for better abrasion resistance in higher foot traffic areas.

Aliphatic urethanes are more light-stable and will not yellow as quickly as cheaper coatings, like aromatic epoxies. If you're coating an area exposed to UV light, make sure that both your coating materials and your colored media, whether pigment or flake, are tested for UV-stability.
