I have come to notice that certain HSV noise filter values applied to a uniform background colour look horrible when viewed on an LCD screen under certain viewing angles. This is more noticeable on (cheap?) laptop/notebook screens.
Here are two contrasting specimen, made with the GIMP HSV noise filter for the RGB colour #F3F3E9.
Below background becomes coarsely grained and patchy on LCD screens under certain viewing angles. It was created by applying the HSV noise filter with the following parameters:
- Holdness = 2 - Hue = 0 - Saturation = 0 - Value = 14
Below background is less offending. However, on an analogue CRT screen the grain becomes barely visible. GIMP HSV noise filter parameters are:
- Holdness = 4 - Hue = 3 - Saturation = 13 - Value = 13
