Besides it's appeal, I think it would be beautifully intimate, your playmate entangled in a soft rainbow glow amidst surrounding darkness. You being in close enough proximity to see those needy eyes sparkle with want from underneath you. Their untouched skin patched in various colors until you complete the palette with a man-made aesthetic from your mouth. Oh and the marvelous moans and pleas theirs make in complement to the rustling sound of active motion from the lights detaining their body as you have your way with them.
