Purple Haze?

I tried Ben's Brazil profile today and noticed strange colours from my LCD. The photo doesn't reproduce the purple colour too well but that yellow is not a reflection from anywhere.

After cool down the screen had mainly returned to normal.

I can't say I've noticed this before. I do however see a high fan speed when comparing to th classic profile

Classic is dark blue. Not too sure if this accounts for it.

I haven't noticed any screen colour change while roasting with mine...
Fan curve is similar if note exactly same as Firestater so I do not think much effect on that part?

Chris?

The colour change does happen for many of our roasters. It is related to how long the machine has been on so I believe it is caused by temperature. It is not a cause for concern apart from the fact that it doesn't look so good.
