rhetorical question...

Wiki: Beige: Cosmic Latte wrote:Cosmic latte is a name assigned in 2002 to the average color of the universe (derived from a sampling of the electromagnetic radiation from 200,000 galaxies), given by a team of astronomers from Johns Hopkins University.

nz1m wrote:Color? Additive color? Subtractive color? Transmissive color? Reflective color? Is black a color? In reflective coloring it is. In spectral color is it? I'd suspect a lot of analytics and math when in to determining the exact "color" of the electromatic spectral spectrum. But the brain, the TV, the computer, printing requires additive black, or mixing RGB or CMYK to generate black. Then there is spot black. There are shades of black, usually referred to as percentages of black and white mixed together. Or 100% tiny black dots spaced appropriately over a white background to give the allusion of gray.

So for the sake of this argument, and this beige calculation, let's call it the COLOR of LIGHT, not just color. What say you?

About this pale green color Wikipedia says, "The original and incorrect color thought to describe the universe was 'cosmic turquoise' due to an error in the way that the software used had calculated the shade." But the pale green color shown is 153R + 255G + 204B which anyone will recognize as the "web safe" color 99FFCC that I wouldn't believe without verification.

Think about it, though: In this one image, you've seen every sight there is to see in the universe...

There is no color change in the past 7+ years in these pictures, but they do show that the universe is expanding faster than previously believed; in 2002 the universe was 625 x 475 pixels, while by 2009 it had grown to 900 x 600 pixels.

nadia wrote:What gives cheese its color?

Milk is essentially white whether it comes from a cow, sheep or goat. So why are there so many colors of cheese? A couple of different factors come into play here, the primary ones being:

- Milk type. Goat cheese is always white because the beta carotene in the goat’s diet is broken down into Vitamin A before it enters the animal’s milk. Sheep and cows retain the beta carotene in their milk, giving their cheeses a yellowish color.

- Animal diet. Cheese color can vary depending on what the animals have been eating. Cows grazing on alpine flowers and fresh grass will have higher levels of beta carotene in their milk than cows who have been feeding on hay.

- Added colorant. Often a natural coloring annatto will be added to cow and sheep’s milk cheeses to create a more uniform and deeper colored cheese (most notable with bright orange or red cheddars). The brighter and more uniform color is used primarily to disguise seasonal fluctuations in the animal’s diet, as well as a marketing tool (some consider brighter to be better, or sharper tasting).
