Drawing a specific color in the image editor I'm trying to do something that seems very elementary but I can't figure it out: I want to make a 8x1 px bitmap and give each pixel a specific value in the Blender image editor. My first problem is that I can't resize the brush ('Draw' tool) small enough; it's always bigger than 1 pixel so I draw on other pixels. Secondly I can't find a blend mode that will just assign the color that I chose in the Color Picker; it always adjusts the existing color.
I think your falloff should be adjusted. Mine stops after radius 1 (2 is the diameter)
I was able to paint pixels successfully without modifying other pixels. Let me know if you need the blend file.
Cheers!
