Color Accessible Web Design Tools
Most graphics designers have excellent eye sight, at least with focus correction, and assume that viewers of their creations do also. A layout might start with theme colors selected from a color circle according to mono, triad, tetrad theories, with block dimensions following the classic golden ratio. Modern computer monitors can handle over 167 million colors, far beyond any printer.
However, an estimated 9 to 13 percent of males and under one percent of female population have some form of color blindness. Ouch!
A web search found these definitions for color blindness, compared to statistically normal eyes. Protanopia means difficulties to distinguish between blue and green colors and also between red and green colors, or no sensitivity to red. Deuteranopia is blindness to green. Tritanopia is blindness to blue-yellow.
Fortunately the World Wide Web Consortium (W3C.com) has included color contrast ratio algorithm in their guidelines, and free tools are available to measure the contrast ratios between colors for the main descriptions of color blindness. One such, Colour Contrast Analyser Version 2.0 ("CCA"), can be downloaded from www.paciellogroup.com/resources/contrast-analyser.html">http://www.paciellogroup.com/resources/contrast-analyser.html
Note that black text on white background, or the reverse, has a ratio above 20 for all 4 eye conditions, and 21 seems to be the maximum. On the other end, a ratio of 1 means a problem.
Also note that color combinations selected by a young-ish designer of fantasy video games might be decipherable by a senior citizen, but require more effort than the viewer is willing to invest.
Here are some examples of contrast ratios measured with CCA. The tool accepts inputs in hexadecimal or color slider positions. On this tool, black & white have the greatest contrast ratio of 21 for normal eyes and 20.9 for protanopia, deuteranopia, tritanopia. The "primary" (RGB) colors on white range from 1.4 (green) to 20.4 (blue). RGB on black range from 1 (blue) to 15.3 (green). Thus Green on White and Blue on Black are terrible choices.

It seems that a minimum contrast ratio of 4 is a good target, so "RGB" is not safe. The combinations used for text on http://WriteAid.us provide contrast ratios from 4.5 to 20.9.
Web designers who ignore color blindness can lose or confuse about 10 percent of potential viewers. The extra effort to avoid this problem is not great.
The problem with the future is that it's always 3 to 5 years away. Nevertheless, what you're looking at is what Philips and Dimenco, a small company of ex-Philips engineers, say will be coming to the consumer television market as early as 2013 -- earlier if you're in the professional advertising business or just want to view your family photos on a small 3D photo frame. Just remember that Philips has been showing off variations of the glasses-free technology behind this prototype lenticular lens television for years, so we're not getting our hopes up. Nevertheless, Dimenco assured us that the path to the consumer market for its 3D display is clear. 
Yeah, we spied a few of LG's new 31-inch, 2.9mm thick displays the other day, but we hadn't seen the standard TV-like configurations -- which don't mean too much, because this is still a prototype, but they're a comfort all the same. We also managed to peep a 3D setup with the screens, which used polarized glasses and was surprisingly sharp. We promised ourselves it would just be a quick look, and that we had important things to do today, and that we really don't need a new TV all that much... but three hours later we found ourselves still planted in the same spot, a small trickle of drool dripping all over our camera gear. When we finally managed to snap out of it, we clicked a few stills and grabbed a video of one of the screens spinning before running out of the LG booth with our eyes shut tight and desire still raging in our heart. 
We're excited about the Boxee Box, and the new-look Apple TV is intriguing, but no single box is as good as a box that doesn't exist yet does the same stuff. Confused? Sit down, let us explain. That's the point Plex is making in announcing its new partnership with LG, which will integrate Plex software into its 2011 Netcast HDTVs and Blu-ray players. Plex enables the same sort of functionality as those smart little boxes mentioned above, letting you serve content from a machine running OS X and push it to your TV or to a mobile device (iPhone and iPad right now, Android coming). Plex also supports all the major online streamers, like Netflix, Hulu, and even the BBC iPlayer. Lack of PC support is something of a bummer, but a Windows version is said to be coming, so even your beige box can soon get in on the box-free fun.
