change color map to grayscale or rainbow

Post by saxonfahrer »

Hello,
i'm looking for a methode to change the color map to grey scale or rainbow colors for simpler import to another programm.
I didn't tried every pre-configurated color map but all looks like they uses different alpha-values (darker and "whiter") within the scale.
Unfortuantley i also didn't the principle of the color map gui to create my one rainbow-like color map.

Is the a methode to convert to gray scale or a color map which is rainbow-like?

Best regards,
saxonfahrer
