Are there mirrors/panels capable of reflecting designated color wavelengths?

Main Question or Discussion Point

I was thinking today about whether or not mirroring could be altered to reflect only certain wavelengths of the spectrum? I couldn't think of specified way to do such a thing, thought maybe some more adapted minds could lend some advice. Thanks for any help on the topic.

Yes. These are called dichroic filters, which transmit or reflect certain wavelengths by using layers of dielectrics. Look it up.

Paint? How narrow a spectrum do you want?
