Stitch Software Image Editing

Okay, I have one big problem with the stitch software and it’s probably an easy fix. We need a green/magenta slider to edit color.

Also, does anyone know why when you change the color temperature the image either goes really green or really red/magenta? Does anyone else have that problem?

I never get this problem in a primary space- usually background. I often drop the saturation if I’ve elevated it, but I know what you mean. I’d like a “reduce majenta” slider along with blue and yellow.
