Working with FM colors

1st Question (Meaning of 'Don't print')

1. Create a new blank page.
2. Add a new color: View > Color > Definitions, for example
   • Name: gold
   • Print As: 'Don't print'
   • Model: RGB
   • #: FFD700
3. Assign the new color to a paragraph tag.
4. Write some text in a paragraph.
5. Assign the aforementioned paragraph tag to the paragraph. The text is formatted with the new color (gold).
6. (optional): Write some more text in another paragraph using another paragraph tag.
7. Print the document (Adobe PDF printer).

The text, formatted with the 'Don't print' color (gold), is still visible:

What did I do wrong? What's the meaning of 'Don't print'?

2nd Question (RGB or CMYK?)

Matt: All [16] default FrameMaker colors are RGB colors.

In InDesign, there is an icon showing the color model of a color (RGB or CMYK).

But in FrameMaker, how can I find out, wether a color is a RGB color or a CMYK color?

3rd Question (Conversion of the color models)

When exploring the FM color definitions (View > Color > Definitions), one can change the color model from RGB to CMYK and vice versa (FM converts the colors.). But how is the FM conversion done? Other tools (InDesign, LibreOffice, etc.) provide different color conversions from RGB to CMYK. Two examples:

Forest Green:

FrameMaker-RGB: (33, 138, 33)

FrameMaker-CMYK: (41%, 0%, 41%, 46%)

InDesign-CMYK: (83%, 19%, 100%, 6%)

LibreOffice-CMYK: (76%, 0%, 76%, 46%)

Olive:

FrameMaker-RGB: (102, 102, 0)

FrameMaker-CMYK: (0%, 0%, 40%, 60%)

InDesign-CMYK: (57%, 41%, 100%, 33%)

LibreOffice-CMYK: (0%, 0%, 100%, 60%)

Can someone please explain the different conversions? Many thanks.
