roomsetting to strip HTML colours (as bridged from IRC)

[ara4n]

We need to have ability to strip HTML colors, because in some cases it extremely reduces text legibility, see linked issue below. Suggested solution to solve this issue is to add a generic config option, so you can manually turn off irc-like text coloring on demand.

Edited to add details.
First issue describing problems: #9366

this is a particularly good candidate for granular settings, too - given you might want to enforce it for a room, or for an account, or even for a device (if devices have different themes).

Should this be just font colour attr or also 'data-mx-bg-color', 'data-mx-color'
as bridged from IRC implies just the colour attr, but the other two are other ways of sneaking colour in, that won't enter via the bridge

is there away to send different colors for light and dark themes?
e.g. for light themes, darkblue and for dark theme lightblue?

this is not readable on an element with dark theme enabled:

<font color="blue">Info</font>

[t3chguy]

No, that is not something the Matrix spec allows @genofire - but it does allow setting a foreground and background colour so you can ensure legibility.

Hmm, should element render "default" colors dedicated by light and dark mode?
e.g. send-color: <font color="{{ sendColor}}">Info</font>

send-color	light-theme	dark-theme	comment
red	red	red	always good readable
blue	blue	lightblue
green	darkgreen	green
yellow	orange	yellow

that wouldn't work with custom themes, where someone's background might be red or blue or pink or whatever e.g. https://github.com/aaronraimist/element-themes
