Apple Silicon M1 supports “billion of colors” a.k.a. HDR 10-bit output

Millions of colors is most likely 8bit color with 16.7 million colors. Still in use today.

7 bit color would also count as "millions of colors", but I don't remember any GPU ever offering it as a display mode.

Unless I'm missing something (dithering?), 24bit color is 16.7M. 8 bit color is 256 colors, 7 is 128 colors.

8*3=24, 8 bit per channel is a description they use in visual effects. Recently the rest of the computing industry started using it. Yes, confusing.

Ah, okay. I'm using old terminology I guess. Appreciate the gentle pointer.

I asked the same question on starting a vfx job many years back. 8-bit, 256 colors for a feature film? Impossible, that would make it look like .gif or Windows95, right?

you're correct. I assume they're referring to 8bit per colour (RGB) which is 24bit colour (True Colour) 16.7M
