I'd go the other way - white or very light grey for the text, but as long as the contrast is high it should be fine,
For colours I have always found that following the heraldic schema helps - the colours are divided into metals (yellow, white) and colours (blue, red, purple, black, green and orange), to get decent contrast use one from one group and one from the other (so no red on black for example, but white or yellow on black are fine). It is basic, but it does give you a decent starting point.
With that being said...
If you expect your customers to print the stat block out, try to minimise the large areas of block colour - at the moment Mongooses stat blocks for NPCs, ships and creatures are dreadful to print...
