Any real amount of power delivered by this will need more than a small receiver. Just being in a sidelobe or getting hit by a reflection would cook you so there will have to be a fairly large no go zone around it. Even the best directed arrays in space have serious divergence.

You still have to build a receiving station. Why not build a generator? I fail to see the use case here especially considering even if they develop the technology it will still be pretty inefficient and if it can deliver truly useful power it will be trivial to turn it into a weapon.

There are intrinsic problems with the idea.

Shades are independent colors. Even if they don't have a name. The entire concept of color is a human conceptual one not one that exists in physics. When you get right down to it there are no natural colors that are actually one color. Even the best single wavelength emitters output in a range around an average wavelength not one color.

A typical human can only see about a million colors we can't differentiate finer than that.

People trained with color reference swaths can do better
