Yes—adjustable-color on-camera LED lights do exist, and they’re commonly sold with color temperature control for video and close-range use.

But for still photography flash, not really in the same way. A true flash/strobe produces far more light than LEDs, so an "LED flash" is generally not a practical substitute for a normal hot-shoe flash except at very short distances. Also, using an LCD or similar filter over a flash would waste a lot of light, which is why direct-emitting LEDs are used for variable-color continuous lighting instead.

So the practical answer is:

• For continuous lighting: yes, look for on-camera LED lights with adjustable color temperature.
• For photographic flash/strobes: conventional flashes don’t typically vary color this way; they’re much more powerful, and matching ambient color is usually handled by other means rather than a phone-style dual-LED system.
