I think you need to get rid of the alpha channel.any one better with photo shop than i am, this is changing the chorma on the image, it actually changes when you adjust the colour filter,

I don’t have Photoshop, but if I do the following in GIMP:
- Colours →Components → Decompose, model: RGBA, decompose to layers
- in the new image: Colours →Components → Compose, model: RGB
- in the new image: Colours → Hue-Chroma, set chroma to +100
So it looks like GIMP’s hue-chroma adjustment filter gives a different line pattern than Photoshop’s. (Edit #3: the OP uses GIMP as well, so it’s probably a difference between GIMP versions.)
(Edit #1: also GIMP’s colourcube analysis tool reports there’s only one unique colour in the original image, so I guess the lines are a filter artefact and we’re on the wrong path.)
(Edit #2: the same pattern appears if I do chroma+100 on a freshly created all-white image with the same dimensions, so yeah, definitely an artefact.)
