Re: [libreoffice-marketing] branding colors - missmatch

Ahah, i had not considered that darker colours might print lighter and thus end 
up matching the colours of the website.

Does the wiki give details of the colour values to be used on monitors along 
with colours to be used when printing?

Regards from
Tom :)

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
