pink square tan demo

If I hoover the mouse pointer over the word "tan" konsole produces a strange pink square.  I've not noticed it do this for any other word and I've not down anything that makes "tan" special (such as search).  It doesn't work for "ta" and it doesn't work for the string "tan" inside another string (eg stan and tango are normal). It respects certain white space so " tan " " tan(" ")tan" "*tan" both produce the square but "stan" doesn't.

I can only presume this is some feature I'm unaware of gone wrong but what it is I've no idea.

Thst would be the show color when hovering option. You would get a similar
result hovering over the words blue or red, or over some color in
hexadecimal format.

Ok - that works - colours - I suppose "tan" might be a colour.

What possible reason is there for coding this into konsole? how do I turn this off? I can't help thinking this is completely un-useful bloat!

It uses the color names found in https://www.w3.org/TR/SVG11/types.html#ColorKeywords.

> ... how do I turn this off?

The setting is "Preview Colors on hover" in the profile's Mouse -> Miscellaneous settings.

n.b. Prior to Konsole version 22.07 the setting was called "Allow Color Filters". As of version 24.05 (released 23 May 2024), the preview has a caption.

Thanks - I've disabled it.

I can't really understand why there might be a usage case for such a feature!  (especially enabled by default)

dont be closed minded.

there is a lot of developers that uses konsole + a text editor to program
graphical interfaces and by hovering on a hexadecimal color makes their
lifes easier.

its essily disabled, and its enabled by default for discoverability.

if you think less than 1kb of code is bloat, man, nothing to say here.
