Yup, with the Herpstat Pro and Herpstat ND you can pay (and I have paid) a few extra dollars to get a blue LCD instead of the standard green one. I'd love to see this option with the VE's.
Exactly, little stuff like LCD color definitely shouldn't be as much as a priority as the quality and dependability, but it certainly is a consideration. If you are putting so much money into a quality thermostat I personally think you should be able to throw in a few dollars more to make it a little more aesthetically pleasing.
