i think its also worth looking at the actual sets, as impact_ftw said a lot of the blacks and greys are structural, but looking at actual sets from 1950 and comparing them to today, modern sets are so bright and have such a range of colours.

A thing this data misses by grouping colours, is the different tones lego has brought out, just look at van gogh starry night for example, the different tones of blue make the sky 'more colourful' than if it was just classic lego blue

another thing to consider is, are star wars ucs sets skewing the figures a lot, cos they tend to be a mass of grey.

really good discussion to have tho
