VGA could not do truecolor; the original VGA at this resolution 640x480 could do 16 colors, i.e. 4 bits per pixel and that means 150 kB framebuffer. It could do 256 colors with lower resolution (oficially 320x200, or "mode-x" 320x240).
VGA came with 256 kB RAM onboard. Then, in the early 90's, SVGA came with 512 kB and 1 MB onboard, and it could do 800x600, 1024x768 and 1280x1024. The main RAM would be around 4 MB for the midrange computer. It took until mid-90, that you could get 4 or 8 MB SVGA, that could also do hicolor and truecolor.
