I was wrong today.
A CSS Stylesheet had a style with a backgound-color setting of #fff:

background-color:#fff;

And another style with a color of #aaaaaa:

background-color:#aaaaaa;

My colleague commented that for consistency they should both be a six digit hex-code, to which I agreed. But I was mistaken as to what the six digit hex equivalent of #fff was.

I thought it was #fff000.

I can also see what fold might assume its #000fff.

Or even #f0f0f0;

But actually, it is #ffffff. The same is true for #aaa and #aaaaaa. And #aba is actually #aabbaa.

For a good explanation as to why this might be, refer to the following links:
