Fix_temperature_colour_part3

The temperature as displayed in the GUI is red on blue
(which means the drive temperature is higher than max
limit but less than the critical limit.

This bug appeared when critical limit = NO_TEMPERATURE_DATA
so that in such a situation the text would be red on black
despite the drive temperature being within normal operating
range.
