Please can someone tell me how to set Picamera2 to monochrome?

However, that is the result of a quick google.

If the link does not provide a solution then more information is needed.

Ralston18: Thanks for your reply. I should have described my project. I am making a bird box camera which is to work with an IR light source. The NoIR camera was giving a very pink image and I thought that if I could turn its response to monochrome in visible light, it might make the IR image more acceptable. After some experimentation, I have found that setting "ColourGains" to (1.0, 1.0) produces an IR image which is near enough to black and white for my purposes. Thanks again for taking an interest in my problem.

You are welcome.
