There are contrast issues in some of the logos at
<https://wiki.documentfoundation.org/images/2/25/LibreOffice_LogoImprovements2016_Ideation.png>.
(The criterion is use for contrast comes from Success Criterion 1.4.3 in
the W3C's Web Content Accessibility Guidelines (WCAG) 2.0:
<https://www.w3.org/TR/2008/REC-WCAG20-20081211/#visual-audio-contrast-contrast>.
 
I used the Colour Contrast Analyser from
<https://www.paciellogroup.com/resources/contrastanalyser/> to check the
contrast.)

For example, in the logos above the first horizontal line:
* in the logo with the green background, the contrast varies on where
you check (due to the gradient):
** close to the "L": #FFFFFF on #36B923: contrast ratio of 2.59 to 1
** close to the other end of the name: #FFFFFF on #18A203: contrast
ratio of 3.38 to 1
* in the logo with the grey background, the contrast is OK: #FFFFFF on
#666666: contrast ratio of 5.74 to 1

The green letters on a white background also have insufficient contrast.
(Unfortunately, I can't continue checking; the image with the logos no
longer diplays in my browser.)

This is obviously not a new issue. For example, the splash screen in
LibreOffice 4.0.4.2 (the version on my PC) also has white text on a
green background with a contrast ratio of 2.86 to 1, which is much too
low, even for big letters.

Best regards,

Christophe
