I have trouble distinguishing the green and grey on
my MacBook.  Herbert, who is colorblind, can just barely
distinguish that there are two different colors.  Note
that 1 of 12 men are colorblind so this is actually quite
common.  I would suggest using a pale transparent image
to suggest absent information.  I would have no idea how
to change the appearance on my screen and would be afraid
to change it in case it affected all my browser use.  There
is no description of how to change the appearance.  And
the casual user wouldn't be bothered. - i.e. everyone.

     The black parts of the logos are hard to see against the
dark green background.

     For published/unpublished why not have two different
logos?  Perhaps a "printed" word vs. a "handwritten" word.
Or use the current logo for published and a pen plus sheet of
paper, giving the idea of being written or edited, for
unpublished.  Or you could keep the current logo and include
the year of publication in the image, using a ? for unpublished.

     The general idea is wonderful as there were only a few
people who identify all proteins from their entry names back in
the days when there were hundreds of entries.  By now, I
suspect even Jane Richardson doesn't know them all.

Good idea.

But the icons for published/unpublished, protein present/protein absent, nucleotide present/nucleotide absent and ligand present/ligand absent look identical to me - I have to read the alt text.

Is there some colour thing going on here which is invisible to protanopes?

Thanks.

Read The Friendly Manual :-)   pdbe.org/pdbprints

The default is "EMBL green" but the icons can also be rendered as transparent images and then whatever colour you set the background to is shown through them.

Grey background means absence of feature or information.

PS: Earlier thoughts of using "Brilliant Orange" as the default colour were abandoned after the blackest day in Dutch history.
