[libreoffice-design] Re: [libreoffice-marketing] branding colors - missmatch

Hi Thomas, all,

CC'ing the design list as I think this topic should be discussed there.

Sorry - but as I don't possess Adobe CS4, I can't reproduce your problem.

Christoph Noack is the one who provided these colors - based on some 
thoughts from the design team.

I don't understand what's the problem with the values written on the 
wiki site. As they will be printed on "real" material, they will look 
different from their representation on the web.

This file shows really dark green tones - and imported in Inkscape it 
reads #007c37 for the darker and #1cb24b for the lighter green.

None of them is #18a303 what it should be.

I could send you a screenshot (or the SVG file), but I assume that this 
result is based on several conversions between applications, file 
formats and color models, so it would probably not help.

As we can't avoid conversion problems with different applications, we 
should stay with the color codes as far as possible. Even with the same 
color codes they will look different when presented on different 
monitors or printed by different printers.

(I remember a strange color problem with Adobe conversion to CMYK back 
in 2006  on the OOo-Art list, where only Illustrator showed different 
colors or converted to other values while all the other applications 
showed the same color. Can't search the archive at the moment, but it 
was related to the Art Style guide we created then - and perhaps a 
comment made it in the guide too)

So please use
HEX 18a303
RGB (24,136,3)
CMYK (85,0,98,36)

I'll send you a file converted to "plain SVG" offlist. Perhaps you can 
open this one.

I don't know enough about color definition in PNG. But the logo has been 
exported from Inkscape with the right color, so it might be possible to 
find out, how the color values are stored.

Did you have a look at the file with a different application than 
Illustrator? Does the color differ?
> > Well, this values are really different!

Yes indeed.
> > So, what to do?

Ii just tried to save a SVG file containing a green rectangle and open 
it in an editor. It reads:

style="color:#000000;fill:#18a303;fill-opacity:1 ...

The exported PNG file doesn't show any readable values because it is 
compressed, I suggest.

But as well in Inkscape as in GIMP the color stays #18a303. so I don't 
know if there is a problem with the .png file you got or with the color 
rendering at yours or somewhere in-between.

Perhaps the SVG file can be opened...

Best regards

Bernhard
