background and text no matter their initial color
Classification: Applications

Version: 22.08.2

OS: Linux
Status: REPORTED

image with pdf page colors
Some pdf files have text pages that are in fact images of book text pages with
multiple colors and shades. Inverting the colors or changing the colors only
imposes two selected colors onto that and readability is not improved.
STEPS TO REPRODUCE
1. Open a page like that in part 1 of attachment, setting a "light"
(background) color of #1b1e20, and a "dark" (font) color of #1b1e20
OR:
2. invert colors.
OBSERVED RESULT
1. it looks like the page part 2 of attachment; the background color is not
uniform and lighter than expected (mostly about #434A50); the text color is
darker than expected (about #C5D8E9)
OR:
2. it looks like part 3 of attachment; the background is bright blue (#1F446E)
EXPECTED RESULT
The colors should be those selected initially.
