Intrument Cluster Temperature Question

The temps are displayed in blue until they reach normal operating temperature and then turn white (then red if you push it hard). My water temp recently stopped going blue, even though I'm 98+% sure 69 Fahrenheit isn't supposed to be in the "white range". Is this correct?
Anyone know when these should turn blue to white to red? (Temps are different for oil and water obviously)
I've only ever seen the oil temp blue till the magic 176F when it then gets put in S+.
On the flip side, I've also never seen red for the gauge either, but never tracked the car, so my quick highway sprints only ever get her up to ~240ish (and then she's still in the white).
The manual (pg 219) states "if the engine oil temperature is below 176F (80C) the oil temperature is shown in blue. Avoid driving at full engine output during this time."
(so also don't reference red, nor coolant temp color change)
