Blue light on Groclock - too stimulating?

[milkyman]

Ds 3.5 takes no notice of his groclock and it is nearer to his face now he has moved rooms. I have read that blue light is too stimulating and red ahould be used? He hates change though so not sure whether to remove the clock?

If he takes no notice of it I would get rid.

The benefit then is that you can hide it for a year or so and next year bring the groclock out again and the newness of it may mean he pays more attention to it once a bit older.
