You might not know this, but on Airbus, there can be magenta coloured altitude messages on the FMA, which are constraints found in the FMGC on the programmed route, and blue (actually cyan) coloured altitudes which you set on the glareshield.
An example of magenta altitude messages would be an intermediate level off on a SID. If there is a constraint of, say, 5000’ and you are cleared to FL80, if you pull the Alt knob, the Airbus will ignore any alt restrictions below FL80 and climb straight up to that level. If you push the altitude knob, it will still climb to FL80 but will obey any constraints below FL80, (and show them in magenta).
Therefore it is important to report the colour as well as the message so you can both confirm what is going on.
