colors - Does rec 709 for HD video and rec 2020 for 4k video 10 bit represent same colour -


does 10 bit rec 709 hd video , 10 bit rec 2020 4k video represent same colour..i read books compared 8 bit color 10 bit color represents more color information, how 10 bit color of rec 709 , rec 2020 differ each other, or represent same color.

the bit depth not relevant when discussing whether 2 color spaces represent same color. bit depth concerned how accurately colors represented within space in way similar how significant digits determine how accurate numerical data is. it's little asking if range 1.00-10.00 equals range 0.00-100.00 because both ranges express numbers 2 significant digits.

the information need in order answer whether numbers in 2 color spaces represent same colors primaries of spaces in question. determines how large color space — colors space capable or representing. in case rec 2020 , rec 709 vastly different. rec 2020 larger space primaries pure spectral colors. example, in rec 2020 pure red, represented rgb triple [100%, 0, 0] color of pure 630 nm light. rec 709 can't come close representing color regardless of bit depth. it's 100% red less saturated , no amount of bit depth change that.
