Mike, I know absolutely zilch about what running a website entails, so please bear with me.
What I'm wondering is: how hard would it be to simply have an options menu where users could decide on their own colours ?
I usually log in on Army.ca, but there are/were three other options to choose from, each with its own distinctive colours.
I've logged in on all of them at one time or another.
Frankly I always found the light blue on the Airforce site to be the easiest on my eyes (unfortunately, being an Airforce site, I could never get it to work before noon ...grinning, ducking).
Is a user-customizable-thingamajiggy a viable option ?
