minus-squarepetrol_sniff_king@lemmy.blahaj.zonelinkfedilinkarrow-up10·2 months agoThat’d be nice. 90 and 120 are rolling through the greens. Are posters mostly green? That seems odd to me.
minus-squarebob_lemon@feddit.orglinkfedilinkarrow-up17·2 months agoThe problem is that averaging hue makes no sense at all because hue is not a longest scale. If you take a red poster (0) and a blue poster (240), it averages to green. Or take red (0) and red (359), averaging to cyan (180).
minus-squareflying_sheep@lemmy.mllinkfedilinkarrow-up7·2 months agoThe average of 0° and 359° is obviously 359.5°. it’s a radial scale.
minus-squarebob_lemon@feddit.orglinkfedilinkarrow-up9·2 months agoBy that logic, the average of red and cyan is both purple and lime. Still useless.
minus-squareflying_sheep@lemmy.mllinkfedilinkarrow-up2arrow-down1·2 months agoNot if there is a clear trend. If most movie posters are blue, three average will be blue. But i agree, it is useless if there is no clear trend.
minus-squareStarbuncle@lemmy.calinkfedilinkEnglisharrow-up5·2 months agoI wouldn’t trust someone who tried to visualize hue like this to make that calculation correctly.
minus-squareflying_sheep@lemmy.mllinkfedilinkarrow-up6·2 months agoYou know what, I completely agree.
minus-squareStarbuncle@lemmy.calinkfedilinkEnglisharrow-up2·2 months agoIt would have made more sense if they had shown the distribution of hue as a polar graph and just had one every decade to show how it changes over time.
