Lab Readout visual color feedback of the numbers

It would be nice if the "a" and "b" readout values in Lab mode change color to reflect the meaning of the values.So if "a" is negative the value readouts show green numbers and if "a" i positive the color of the numbers are magenta and "b" negative shows blue numbers and "b" positive shows yellow numbers. This would be awesome and give C1 even more uniqueness.
