Oil leak. Clueless

Hi I had an little oil leak on my drive 1 week ago , its since dried but then last night it poured it down for the first time in a week and I woke up to multicoloured patches on my drive could these be due to the oil leak 1 week ago? Bearing in mind no cars have been on the drive since :) thanks

If "poured it down" means it rained, the patches were probably moved around by the water. When water and oil is mixed, the oil will float on the top and the reflected light can appear in different colors.
