Mordechai is totally right in that it is hue that makes it difficult, but it is only within the specific context of combining the two (either Red/Green or Blue/Green).
I had a series of progressively more advanced CB tests when I went to join the Army, and ended up with a rating of 19, with 20 being the worst (on their scale anyway). I can totally see the difference between Red and Green, and in
99.9 percent of the time it makes no difference to anything. The only time I notice it is when someone wants me to look at the pretty red bird sitting in the green tree (unless it moves, I will NEVER find it), or once when I was driving past a field everyone wanted me to stop and take photos and it took me 10 mins to work out it was an apple orchid in full bloom- all I could see was a bunch of boring trees. The reason you can't be an electrician is that if there is a red wire in a bundle containing a lot of green ones, there is little chance you would see it.
I can't ever recall a website that caused me grief. If I have come across one, it would have still been usable for me, I just would not see it that same way as the author.

If it's only red or white letters on a black background, it shouldn't be
a problem in most cases, but it's less than ideal.

It depends on the form of color blindness. For someone with total color
blindness, then yes, it would appear gray, but this form is very rare.
The most common form is red/green. It that case, depending of the
severity, reds and greens do appear to have color, but depending on
which hue, telling the difference between the two is often very difficult.
