How can i guess the color values?

Question

it's really annoying to guess them.

Answer 1

If you already comprehend that those are RGB color components in their hexadecimal representations, just look at the color component with the highest value.
If a number is close to FF for red - it tends towards reddish shades, if for both red and green - towards yellowish and so on. If all three components are equal - it is a shade of gray.

Below are all extreme (basic) examples:
000000 - BLACK
0000FF - BLUE
00FF00 - GREEN
00FFFF - CYAN
FF0000 - RED
FF00FF - MAGENTA
FFFF00 - YELLOW
FFFFFF - WHITE

Answer 2

When you use hexidecimal code #ffffff you have to know that the first 2 stand for red the the next 2 for green and the last 2 for blue and how we learned in school you can mix red green and blue to get any other color :D

Answer 3

You mean hex values, like #FFF000? You can search online for a "hex colour picker" to find hex values.
