Colour schemes are hard.

Can't quite decide if to go for a dark grey background or a more saturated and brighter one. Both versions use the same hues, but different amounts of light and saturation.

The darker one is easier to read in a dimly lit room, while the brighter one is much more comfortable in sunlight. I'm thinking the brighter one might also feel more personal, and might be more memorable, but I'm not sure.

Ideas/thoughts appreciated!
