Color codes, FACE IT app and Fenix 3

Problem is simple.

I created a png/jpg file with colors provided here
https://developer.garmin.com/index.php/blog/post/pro-tip-using-the-bitmap-palette-options
and images doesn't look good on the watch.

Example:

I want solid colors on the watch. Even yelllow is not yellow but with red dots.
Red is grey.

One suggested The best Red is in RGB 255:48:0.


Could anybody list all color codes to use in PC which look 100% solid on the Fenix 3 watch?
