Pygame Changing Hue of Image

Question

I have a question to do with the Python module pygame.

I have seen many posts concerning changing specific pixels from one color to another, although this is not what I want to do. I want to do something similar to what can be done in simple photo editing software such as paint.net, changing the overall color of an image. I could of course change the hue of the image in a photo editing software, but this would lead to lots of images needing to be made and loaded and managed, it would quickly become very tedious. I am hoping that there is some sort of way to change the hue of an image in pygame.

Answer 1

You can do this with Python PIL. Take a look at this question and answer, and especially the original question and answer that they link to:

Answer 2

    '''
    Original post https://www.reddit.com/r/pygame/comments/hprkpr/how_to_change_the_color_of_an_image_in_pygame/
    '''
    
blue_rgb = (0,0,255) red_rgb = (255,0,0) img =
pygame.image.load("sky_picture.png") # loads the picture from the path
given var = pygame.PixelArray(img)
# var.replace(([Colour you want to replace]), [Colour you want]) var.replace((blue_rgb), (red_rgb)) # replaces all blue in the picture
to red del var 
"""
if the picture has some unchanged pixels left it's probably because they are not EXACTLY the rgb given for example (254,0,0) is not
(255,0,0) and won't be changed (to fix this you will have to calculate
the approx number ot just change the main picture)
