Illustrator changes HSB values by itself

[yuliakoposova]

Hi guys,
I have some problems with color while working with HSB. I put certain values, click OK, then I open color picker again, and values are different. 

then I open color picker again, and values are different. 

Color mode is RGB. Why do values change? Is it just rough rounding? 

Thank you.

Yulia,

"Is it just rough rounding?"

It is: HSB is another description of RGB (or CMYK) so if you enter certain HSB values you will have them changed to fit the closest RGB (integer) values. You can see that the RGB values (and # values and CMYK values) are the same.

Obviously, in some cases it is HSB that makes sense.

You can also insert the HSB values in the Color palette.

I guess rounding, the other values don't change.

For my part you are welcome, Yulia.
