Skittles trick turns plate into a rainbow

skittles

Simple DIY rainbow magic with Skittles candies. Form a circle with Skittles on a plate (colours should be in repeated order, preferably according to colours of the rainbow e.g. purple, green, yellow, orange, red), then pour hot water over them. Wait for the magic to unfold right in front of your eyes

Also funny are the various YouTubers attempting to replicate the effect only to end up with a brownish mix of melted candy slime on their plate. Read the rest

The most popular website colors

colors

This image depicts the most commonly-found stylesheet colors on the web's top sites—Paul Hebert did an amazing amount of analysis and this is just one of the intriguing visualizations he came up with.

Most of these are obvious staples, especially HTML red and blue, though it's interesting how far the blue "cluster" is from the default blue hue, whereas the red cluster merely modifies the saturation and lightness. This might be influenced by various "studies" of the most effective link color.

The odd thing is the popularity of #d2b48c (triggered by the "Tan" HTML color name), which appears to be the single most popular nonblack color after #0000FF (HTML Blue) and #FF0000 (HTML Red). Google uses it somewhere (though I don't see it) Is everyone just following the leader? (UPDATE: see below)

UPDATE: Hebert explains the Tan thing in the comments.

UPDATE: 10/22/2016. Hebert's updated his method to exclude false positives (including the mysterious Tan) Read the rest

Video feedback emulator generates gorgeous glitchy art

videotest

Thea video feedback emulator offers a vague memory of fooling with video cameras and a strong flavor of crisp and fractal generative art, The results lurk somewhere between the decades. Click and drag your results for wild (and often brightly-flickering) variations. The creator explains how it works. [via Github]

What we’ve found most interesting about video feedback is: the sheer complexity of the images it produces through such simply-defined and implemented spacemaps that really only have to do with the relative positioning of two rectangles. It’s somewhat intuitive, but always surprising.

This is all just scratching the surface of the mathematics behind the patterns that video feedback is capable of, but hopefully it’s good enough for a start!

P.S. You’ll notice that many of the “interesting” patterns contain regions of diverse sizes. That is, they appear to have a broad range of spatial frequencies. What’s up with that?

World's "ugliest color" will be used on cigarette packs

untitled

According to an Australian survey, the shit brown color seen above (Pantone 448C, or "Opaque Couché") is the ugliest hue around, reminding respondents of dirt and death. To deter smoking, Australian officials required Opaque Couché to be the main color and cigarette packages and now the UK is following suit. Apparently, Australian officials first referred to the color as "olive green" but the Australian Olive Association was none-too-pleased. Now, Pantone is grumpy about the choice of Opaque Couché. "At the Pantone Color Institute, we consider all colours equally,” Pantone's exec director Leatrice Eiseman told The Guardian. "(There's no such thing as the ugliest color."

The new UK regulations also ban the use of logos, requiring a plain font on the packs.

Aquaman's costume would look different underwater than above

Water filters light. The more water that's above you, the more light is filtered out before it can reach your eyes. The deeper you go, the more this effect alters which colors you can see and how those colors appear, writes Andrew David Thaler at Southern Fried Science. Even at a depth of just 5 meters, reds and oranges become difficult to distinguish from one another. Read the rest

Dyed chicks go for less than a dime

These chicks, dyed in the egg before hatching, were sold as pets for 4 pesos (8 U.S. cents) at a market in Manila, The Philippines. WikiHow offers instructions for dying your own chicks, while The New York Times reports the downside of all that impulse-bought cuteness: humane societies overflowing with now-normal chickens a few weeks after Easter.
