The orange-on-royal blue didn't work as well as I wanted. For now, I'm trying a yellow-on-royal blue. Normally, I don't like the darker colors, but I've really liked using the dark blue as a background color since it provides great contrast. We'll see what happens.
Royal blue and yellow is one of my all-time favorite color schemes, along with royal blue and light blue and then kelly green and gold. But for this blog, I'm looking for schemes that provide great contrast--making it easier to read--while allowing some aesthetic appeal also.
