#90, #91, and #92 are all new slight variations on color, though comparing them to #81, I'm not so sure they are improvements! Regarding color, it's good for you to understand a little bit about how color works in design - from a technical standpoint. Just to let you know, logo design is typically done in CMYK color (Cyan, Magenta, Yellow, and Black), which are the 4 base colors for doing anything in print. Images made to be viewed on screen (a computer monitor or television) are built with RGB color (Red, Green, and Blue). RGB colors tend to be more vibrant than CMYK. So if we select CMYK colors in our software like we should, the color you see on screen will look more dull than it will in print. There's a whole color matching system called PMS (Pantone Matching System) to help designers understand what the colors they choose on screen will look like when printed, and the difference can be dramatic.
This can be tricky when we present logos with CMYK color on the LT website. The color you see on screen, if not altered for print, will look different when printed on paper (you'll typically see a bigger difference when printing professionally than, say, printing out a web page on a laser jet printer). Also, I think you'll find that certain colors may look great against a black background, but might be too light against white. I will definitely keep trying to get the colors just right for you, but if you see any shade of orange, yellow, green, blue, or violet that you really like, please don't hesitate to let me know.
It may be helpful for you to play around on a website for color picking. Adobe has a great color scheme builder at
http://kuler.adobe.com. You can browse the color schemes there and if you find one you like, you can let all the designers know on the contest page. Or you can sign up at the site and build your own color scheme if you want! Adobe Illustrator is one of the software programs that a lot of designers here use, so that's why I recommend using Kuler; plus it gives the values for each color in CMYK and RGB. But there are lots of other websites out there that offer such functionality. You could just do a search for "color picker website" or "color scheme builder" and find lots of tools! I hope this helps! - Lindsey
