Modifying colors for code blocks?

[vor_lord]

I've been using the CODE tags to get monospaced text that I can line up fields properly.

This works just fine except the colors don't have high enough contrast to be read easily.

Could this be changed a bit to have higher contrast?

Here's an example:

Code:

This       Is       Hard      To     Read!
Is         It       Because   I'm    Getting    Old?
