# How to specify a 10-bit color?

When I set the preferences to 32 bpc and sRGB, the color picker switches from displaying 8-bit RGB values [0...255] to decimal RGB values [0...1] out to 4 significant figures. However, the hexadecimal values do not change. For example, RGB[127,127,127] is #7F7F7F and RGB[128,128,128] is #808080. And if I calculate the 10-bit RGB [511,511,511] decimal value, I come up with 0.4995. Similarly RGB[512,512,512] is 0.5005. However, when sliding the color picker up and down the gray scale, the values bounce between 0.498 and 0.502 which are the 8-bit decimal equivalents of 127 and 128.

Therefore, I am wondering how does one go about picking 10-bit colors using the color picker? Or, is there some other way?

Thank you

what I do is change my bpc display from auto to 8-bit although I am in 16 or 32 bpc. like this:

now color values makes sense again

I learned this technique from Ae's Vfx guru Mark Christiansen: After Effects Compositing 02: Matching Foreground to Background. he prefers Decimal, But I am more comfortable with 8bpc.
