[WT-support] color for "Call too long?"

[Franta Bendl]

Hi,

after switch between R1 and R2 (*) is the backround of the input line white. 
If the callsign check is switched on and the callsign is too long (e.g. 
R39WRTC from last weekend) it will be shown in yellow and consequently near 
unreadable.

Is there a possibility to change the colors of checked calls?
