Changing colors for security advisories internal comments

[moeenio]

What's the issue:

Internal comments in Security advisories (a brand new github feature) use a orange color to show their internal state (when advisory is not published).
Should use a distinct color for these in this style.

What version is affected by this problem:

2.6.4

What color would you suggest using here?

Maybe an orange/yellow ?
