An indigo box displayed when hovering "$INDIGO-42" string!

SUMMARY
Konsole diplays a colored square whenever hovering a string which is a color name (in English).

STEPS TO REPRODUCE
1. Open Konsole
2. Type (without quotes) "cd ~/blue" or "echo Red" or "echo $INDIGO-42" . It is not needed to hit ENTER, just display.
3. Hover the mouse pointer over the string with a color name ("blue" or "Red" or "IDIGO".

OBSERVED RESULT
A square with white frame is displayed filled with the color named by the string.

EXPECTED RESULT
Nothing at all.

ADDITIONAL INFORMATION
It's important that the color name is displayed as a single word delimited by blanks of other non-alphanum character.
Likely this an Easter egg and a weird one.

I can see there is a setting within the profiles that controls this (weird?) feature.
Edito Profile --> Mouse --> Miscellaneous --> Preview Colors on hover.
The hint text reads "When positioning the mouse over a hexadecimal color it will be displayed in a frame next to the mouse pointer".
This works only if the "hexadecimal color" is in the form "#HHHHHH[HH]" ('H' being an hexadecimal digit).
If the last two optional digits are defined, a checkerboard is displayed. (See attached screenshots).
It seems also to work with 9 hex digits...
Only thing is that it is not supposed/documented to work with English color names.
I could then dispute when/whether that patterns is actually a hexadecimal color, but I will refrain for that.

At best the bug is in only the hint string that should read:

When positioning the mouse over a hexadecimal color or and English color name it will be displayed in a frame next to the mouse pointer

I am not sure whether the rendering is correct.

I agree that the string should be change to include english colors.  We recently added a "color preview" string to the popup.  I'd have to look at the code to see why 00ff00bb has a checkboard preview.
