No, that's how it looked in PSP format. I enlarged and took a screenshot, so you are seeing some pixelation because of that.  But I wanted to show the larger squares of colour change.

Here is another one showing the stepped look to the colour change that I am seeing inside PSP.  Again, this is an enlarged image so there will be pixelation, but notice the large square "steps" ?  They look about the size of a "bucket"

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
