import pygame
from pygame._sdl2 import video

win=video.Window()
ren=video.Renderer(win)

sf=pygame.image.load("cobweb.png")
sf=pygame.transform.scale(sf, (128,128))

tex.update(sf)

img = video.Image(tex,(0,0,64,64))

tex.color = "red"
img.color = 0x66ccff

This PR seemingly relies on #2349, so that must be merged first.

The PR this PR depended on has been merged, though this still has extra commits? Fix with a rebase?

LGTM

Left a comment, there's also a merge conflict.

The ALL color flag is the same one used by the Color constructor, that's good. It's probably good to just have that be the standard and never support mapped color for Textures?

Thanks!
