#52In response to the observation the average pixel color is surprisingly brown, I'll take today's opportunity to induct some of my fellow HNers into today's lucky 10,000 by linking Technology Connections's "Color is weird" video (https://www.youtube.com/watch?v=wh4aWZRtTwU).

#53Warning, always convert your colors to from sRGB to Linear RGB before doing any math on them, then convert them back to sRGB afterwards for displaying them. sRGB is the familiar color space you all know and love, it's what your display uses, and it's what has those RGB numbers between 0 and 255. But it's not a linear color space. First think of values as being between 0 and 1 instead of 0 and 255. To change sRGB to L…
Even better, convert to HSL or CieLAB. RGB is not at all how our eyes see things.
For the purpose of blurring, there's nothing wrong with linear RGB.
HSL has the angle discontinuity which is really annoying to deal with and sometimes even impossible to work around.
CIELAB should be fine in theory, but it's not what people actually use on their screens, so I've had some problems with it in practice.

#54The best oranges [0] I've had were half green. Fresh from the tree, but still plenty ripe. It's my understanding that oranges for transport to colder countries are picked unripe and ripened in the holds of cargo ships. This ripening process is great at making the skin more orange, and OK at improving the flavour, but nowhere near as good for that as ripening on the tree. So if I saw green patches on my supermarket or…
How green an orange is when ripe has to do with the climate they are grown in. In warm climates with little variation in temperature between day or night, oranges will remain green on the tree even when ripe. If nights get cold enough (~55 F), they will turn orange. That said, in the US, oranges destined for markets de-greened for aesthetic purposes since customers won't generally buy them otherwise.
"How green an orange is when ripe has to do with the climate they are grown in."
Not true for all cultivars. For example, the emerald orange rind always looks like a lime.

That’s like saying green is a yellower blue. It’s all arbitrary.
The names are arbitrary but the underlying color theory is not. Colors are different wavelengths of light and our eyes have sensors that are sensitive to specific wavelengths.
This is not at all how we perceive color.

I'm not familiar with that one and can't seem to find it online. Do you have a link?
Limes will actually turn yellow when ripe. We just pick them early.

#57Wait, is that "local grocery store" selling those oranges for $2.49 _each_?!

#58I'm of the belief that fruit and vegetable packaging is often designed to hide defects, and to make it harder to visually discern how fresh the produce is (on top of not letting you touch it).
Some examples.
Red netting on oranges makes it hard to see imperfections on the skin. Green netting does the same for avocados. Costco sells corn in trays that are cling wrapped with a wrap that is unmistakably designed to hide the ends of the corn (the easiest way to discern if corn has gone bad). Other fruits, and veggies like melons, onions, and potatoes have similar netting with colors that seem to be carefully chosen to maximize visual clutter.
Why aren't all the nets the same color?
Costco sometimes sells pears in plastic trays with multiple creases that cause reflections that make it very difficult to see what the pears inside look like.

#59They really don’t look all that different to my untrained eye - in fact I think it looks “better” without the bag. Maybe I’m loco.
Colours are often very relative though. We usually don't see a single orange on a white background. I'm not sure that would be representitive of real oranges at the shopping mall.
Also that picture (both versions) are the brownish oranges i have ever seen in my life.

Could it also be an "anti-marketing" bias?
We know that other people will not be truthful, misleading even.
We subconsciously know that the bag is orange to manipulate us.
Could it look better because you know it's truthful?
