I would like to give my N900 screen a distinctly
yellowish cast, to make it easier on the eyes at
night, and less disruptive of my melon-tonin'.

Yes, I've tried scribbling it with a yellow highlighter
pen, but the 'ink' remained liquid and rubbed off too
soon.

A piece of yellow cellophane or similar film should work,
but I'm not sure how to make it sticky yet optically
clear (rubber cement, rolled very thin, may work).

The ideal way, though, may be altering some display code,
to give just the tint desired. Is there some n900-
related program that can do this (there's one thread giving
details about this, but it's for the n9; there's also mention
of "screen filters", overlaying a transparent image, for
Android).

W-h-hat? Sorry, I know this post is useless, but I'm actually too speechless to elaborate more.

I just thought, that almost nothing in sphere of N900's hardware modifications can so much surprise me. I was wrong. So. Damn. Wrong.

Maybe you can try to get f.lux or redshift working on maemo. Works really great on my jailbroken iTouch. (Don't shoot me for having an half eaten Apple)

That's actually not a bad idea. Another option is something like this:

http://www.amazon.co.uk/Prince-Lionh...cm_cr-mr-title

It is designed as a sunscreen for car windows. A plastic foil that sticks to the window by pure static force and holds tight as a tick (i.e. does not let go, can withstand opening and closing the window etc). Feel free to read my review. I've used it for over three years without a glitch.

It is a bit large but can be cut to size to fit a phone screen. The tint is light brown, not blue as in the Amazon picture. And it can double as a scratch protector too!

Of course, they may be similar products already tailored for mobile phone screens. Just have a look around.

tfj, that's a great idea. I made test application - it works for not fullscreen windows.

I never removed the original protective film you're supposed
to peel off, so there's protection there. Some kind of yellow
marker may dry properly. Isn't the screen just glass, or is there
some sensitive circuitry or film on the surface?

The outer layer is integrated (as in - you won't disassemble it without breaking it beyond repair) with digitizer, aka "touch layer".

There definitely is a film on the surface (because mine is almost completely peeled off already), I assume it's some sort of scratch protection - because the areas without the film scratch easily.

I would advise a software fix over a hardware one - unless you know you'll never need full brightness.
