Question

How to divide the #000000 – #ffffff interval intro x equal parts, to get x gray colors? Is this possible?

Edit:
More specifically:
I want ‘divide’ the #000000 – #ffffff color range like this:

1. #000000
2. #1E1E1E
3. #282828
4. #515151
5. #5B5B5B
6. #848484
7. #8E8E8E
8. #B7B7B7
9. #C1C1C1
10. #EAEAEA
11. #F4F4F4
12. #FFFFFF

In this list there are 12 colors. (Check out the sgi gray colors here.)

But what if I want not 12 but 32 colors? How to calculate them?
I hope now you understand me 🙂

Answer 1

#000000 is actually RGB with R = #00, G = #00, B = #00

You get a gray color for R = G = B.

#00 – #FF leaves you with 256 possible combinations, so if you wanna exclude white and black (#000000 and #FFFFFF) try something like this:

step = 256 / (x + 2)

So if you want to get 4 grays, step resolves to

step = 256 / (4+2) = 256 / 6 = 43

Transform that from decimal to hex:

step_16 = 43_16 = #2B

The colors would now be:

#2B2B2B
#565656
#818181
