How to blend parts of 3 images into one document?

[It123]

Hi again with another 'dummy' question sorry.  Please tell me what I am doing wrong as I am tying to blend different parts of 3 images onto a single background layer?  Each time I add a mask l am only able to blend parts of 2 images.  Thanks for your help again.

Please post screenshots of the Layers panel after you’ve added one, then two, and then all three masks.

Sorry not sure what you mean .  I have done the first one while trying to add purple to the grass on the left.  When I try to get yellow on the grass it goes back to B&W.  Hope this helps Terry

You need to start from the bottom upwards

 Each time add a mask and invert it, then use a white brush to bring the color back in

Sorry this is lost on me, I'll keep trying though.  Thanks

Thanks again HDVB.  I can see that this works but it makes no sense. Its totally illogical to me to work from the bottom up but thanks again.
