Unlike older cathode ray tube (CRT) displays that scan an electron beam over a phosphor screen to create light, LCD displays are composed of a fixed grid of tricolor pixels that change transparency based on a range of voltage levels provided by the monitor's controller. Without a voltage the pixel is opaque and blocks the screen's backlight from transferring through it, and when a full voltage is applied then the pixel allows full transmittance of the backlight. When this is done over the entire pixel grid in patterns, then you see those patterns on the screen.

Interesting. A few weeks ago, Barnes & Noble starting selling refurbished Nook Color e-readers for $199. Not long after, I started seeing them as low as $179.99 from outlets like 1 Sale A Day. (Incidentally, I ordered one from there; it arrived in about three days, and in mint condition.)

Now, Buy.com has the refurbished Nook Color for $169 shipped. But here's the interesting part: they're selling them on behalf of B&N. Which makes me think something's up.

I have a couple guesses. First, B&N knows a competing color Kindle product … Read more

Being able to match colors on Web pages is an important element of Web design. You may need to match a new page design to an existing one or create custom colors that don't mimic other popular sites. Either way, a color picker is an essential tool to have on hand. Color Cop offers a simple way to read color info, and it does so effectively and in an easy-to-use package.

Color Cop appears as a tiny box that floats on top of your Web page. You can minimize the box while you browse, but it stays on top … Read more

This deal is so likely to sell out, I'm giving you four bonus deals below. Just in case.

Today only, and while supplies last, 1 Sale A Day has the refurbished Barnes & Noble Nook Color e-reader for $179.99 shipped. (Thanks to my buddy Sheldon for sharing this deal!)

One of the features in earlier versions of OS X was that you could change the display color output (or bit depth) in the Displays system preferences. However, in recent versions of OS X Apple has removed this option. If you go to the Displays system preferences you can set the resolution, the brightness for internal and Apple-supplied displays, and rotation and refresh rate options. The colors are now set to be optimal for the display, which means they will default to the highest setting or go to the setting that a particular application requires.

While the color output feature … Read more

Shape Shift is a free, ad-supported puzzler, a classic color-matching game played on a grid, but with a couple of twists that make this app stand out.

The setup should look familiar to fans of the genre: you play on a 9-by-7 grid of colored blocks, and the goal is to match up--and take out--adjacent groups of four or more of the same color. In addition to being red, yellow, orange, green, or blue, each block also has a triangle, square, or circle on it, and you can swap any two blocks that share the same shape. The scoring and … Read more

Crayola has been offering a free iPad coloring app for a while. But Griffin, which makes styli for capacitive touch screens, is now shipping Crayola's full interactive coloring package for the iPad, ColorStudio HD, which includes a Crayola-branded iMarker digital stylus for $29.99.

One of the interesting things about the package is that the app can tell whether the stylus or your finger is touching the screen, which prevents kids from having their fingers accidentally touch the screen and muck up their creations.

You get more than 30 coloring canvasses with the app, and Griffin says there will … Read more
