Summary: cell highlighting invisible to colorblind people
Severity: normal
Classification: Unclassified
OS: Linux (All)
Reporter: [email protected]
Hardware: x86 (IA32)
Status: UNCONFIRMED
Version: 4.1.4.2 release
Component: Spreadsheet
Product: LibreOffice
Created attachment 91464

This is a simulation (using Vischeck) of what it looks like with
colorblindness. Cell D12 (where the pointer is) is highlighted with a red box
as part of the formula but it hardly shows up.
When creating a formula in LibreOffice Calc, selecting a cell to use in the
formula highlights it with a thin red outline. For most users with
colorblindness (~5% of male users), red/black is a very low-contrast pairing.
Red looks very similar to brown or black to most people with colorblindness.
When working in cells that already have a border, this additional highlighting
is nearly invisible.
I've attached an image that shows how it looks to people with colorblindness
(took a screenshot and ran it through Vischeck colorblind-simulation software).
Note that the red highlighting is nearly invisible against the existing black
border.
I'd recommend using blue, instead, as blue/black is a
universally-distinguishable pairing. Blue may not stand out as much as red to
non-colorblind users, but blue will be bright and visible to all users, even
people with colorblindness.
LibreOffice seems to use red frequently to highlight things, but red looks
pretty much like black to people with colorblindness.
