            Bug ID: 134919
           Summary: CMYK generates an RGB
           Product: LibreOffice
           Version: 6.4.5.2 release
          Hardware: All
                OS: All
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: LibreOffice
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: sanipachenko at outlook.com.ar

Description:
When you write the values to generate a pure color (Green, Red, or Blue), it
becomes an RGB value of 255 when they should be different values.

Steps to Reproduce:
1. Clic on font color -> Custom color
2. Write: C-0, M-100, Y-100, K-0
OR
3. Write: C-100, M-100, Y-0, K-0
OR
4. Write: C-100, M-0, Y-100, K-0

Actual Results:
For 2: R=255, G=0, B=0
For 3: R=0, G=0, B=255
For 4: R=0, G=255, B=0

Expected Results:
For 2: R=227, G=6, B=19 (or similar)
For 3: R=49, G=39, B=131 (or similar)
For 4: R=0, G=150, B=64 (or similar)
Values obtained from Illustrator.


Reproducible: Always


User Profile Reset: No



Additional Info:
This conversion happens the same if we put an RGB value: 255, 0, 0 will convert
to 100 values when they are not really correct.
RED CMYK from 255, 0, 0 in RGB: 0%, 95%, 91%, 0%
GREEN CMYK from 0, 255, 0 in RGB: 65%, 0%, 100%, 0%
BLUE CMYK from 0, 0, 255 in RGB: 93%, 75%, 0%, 0%
Values obtained from Illustrator.

This is a problem because the colors that we will see in the documents will not
be real and if the objective is to print, the result could be quite different.
