Feature Request: Support pro-colour space like CIE

[Alex Farlie]

This is a feature request.

Currently Inkscape supports an RGB, CYMK or HSL style of colour input.

However in some applications other colour space are used.

Obviously Inkscape cant support propriatery colour matching like Panatone or NCS, depsite the existence of semi-free matching algoritihms.

However, would it be possible to examine the possibility of supporting a pro-color space which is will documented like the CIE ones (Lab, xyY, sRGB etc.), albiet with conversion back to the Hex level RGB used in SVG?

@Alex - You're very interested in that feature apparently, and it seems you already created a report about it 3-4 months ago ;) (see bug #1582762 <https://bugs.launchpad.net/inkscape/+bug/1582762>)
Do you mind if I mark one of them duplicate of the other?

[Alex Farlie (afarlie)]

No objections to merging the bugs.

The reason for this and the former request is that CIE xyY is what's apparently used to define a 'color-region'(i.e tolerance) used in certain technical applications.

The relevant document I was looking at being -
http://mutcd.fhwa.dot.gov/texts/colorspecfr.pdf

The equivalent British Standard (12899-1) (which I can't link as it's not freeely online) specifies it's colours in a similar manner.

I appreciate that Inkscape isn't necessarily designed with technical applications in mind ( I'm not aware of any "free" CAD systems for drawing road signs though.), but where there is a technical standard, it seems reasonable to make use of it.

Some of the conversion formulae appear to be documented here :-
