random(256) get a random value up to 255 and random(255) up to 254.
The red, green and blue use 8 bits each, which have integer values from 0 to 255, so the first code is the way to go.

Doing random(256) is a bad solution, because if it results in {0, 0, 0}, it will be completely transparent, not black. Most colors will appear faded and unsaturated because of how RGB works. A good solution is to generate a HSV color with fixed saturation and value, but with random hue and then convert it to RGB. This should always give you nice vibrant colors.
