I got on the desktop version today and it is completely unrecognizable as the same game I played before. They changed the title and that was their call, but now it looks just awful. :(
I am currently attempting to play this, but it would not load here. I recommend you download the PC game from the website. It takes some work, but the tech support can assist you in transferring/copy your account to their server. Apparently the game is being "redesigned" with Unity instead of Flash. The game currently appears in a beta testing stage, the best I can describe it. There are missing elements like pop up info boxes, rules, and some of the mechanics are broken. I can play it, but I refrain from using the disenchant feature for fear of shredding all my good cards, as it seems to have a mind of its own. I just want to wish the developers the best of luck with the program and hope they can find the time to forge ahead. They also have a forum so I am sure they would like to hear some feedback there.
The source of color is from long to short wavelengths of light and, correspondingly, from low to high frequency, red, orange, yellow, green, cyan, blue, and violet. Differences in wavelength cause a difference in the perceived hue. While the noticeable difference in wavelength varies in the blue-green and yellow wavelengths, to the more in the longer red and shorter blue wavelengths. Although the human eye can distinguish up to a few hundred hues, when those pure spectral colors are mixed together or diluted with white light, the number of distinguishable hues can be quite high.
In other words, this game is very fun and relaxing. :D
