Change colour of paintbrush tool

Hello,

I have a question concerning the Paintbrush tool in ImageJ.

I am trying to draw lines of various colours using the paintbrush on an image, but I cannot change the colour of the lines. I have tried changing the colour using the dropdown colour menu, as well as making sure the colour I want is in the foreground. It gives me a green line every time.

However, when I choose “Paint on overlay” for the paintbrush or use the Overlay Brush tool, the colour I choose works!

How can I change the colour without using the overlay brush or checking paint on overlay?

Thank you in advance for your assistance.

Julia

I can change the brush color without enabling “Paint on overlay” as long as I am working with an RGB image.
