Edit 2026-06-08: removed the color suggestions as it was concluded that we can remove the color
We already agreed in T8077 that the bold font should only be used if the secret part of a certificate (secret key) is available.
But for S/MIME Root CAs the default appearance is bold font with a blue-with-a-hint-of-purple background:
The contrast here is only 4.63 and which is even in combination with the bold font not sufficient.
Our contrasts for the light green (VS-NfD compliant) and red (not compliant) have a contrast around 13.
Instead of going for a lighter color, we decided to
- use no special default color for root certificates and
- drop the bold font
Then only own certificates will be shown in bold font any more.
For VSD the root CAs should be shown as green or red, the same as for not-root certificates, depending on whether they are VS-compliant or not.
