I wrote the first version of rgba.php as a complement to an article on RGBA that I posted on Februrary 2009. Many people seemed to like the idea and started using it. With their valuable input, I made many changes and released v.1.1 (1.1.1 shortly after I posted the article due to another little fix) [...]
It’s been a while since I posted my little server-side solution for cross-browser RGBA colors (in a nutshell: native rgba for the cool browsers that support it, a PHP-generated image for those that don’t). For features, advantages, disadvantages etc, go see the original post. In this one I’ll only discuss the new version. So, since [...]
If you are a creative professional, or just passionate about colors, please take my survey: http://bit.ly/colorsurvey It will greatly help me to make a future project of our company more usable (some of its features at least) and it only takes a few minutes (it contains 10-19 questions, depending on your responses). Any suggestions, corrections, [...]
As I mentioned in an earlier post of mine, I have to create a color picker, so I’ve already started to write the code for the Color class it’s going to use. I need it to natively support RGB, HSL, Lab and CMYK. And the latter part is causing unexpected trouble. It seems that there [...]

It was my first presentation ever, actually, the first time I talked to an audience for more than 1 minute . This caused some goofs: [...]
As someone who dealed a bit with print design in the past, I consider CMYK colors the easiest color system for humen to understand and manipulate. It’s very similar to what we used as children, when mixing watercolors for our drawings. It makes perfect sense, more than HSL and definately more than RGB. I understand [...]
When using CSS, we can just include both declarations, one using rgba, and one without it, as mentioned in my post on cross-browser RGBA backgrounds. When writing JavaScript however, it’s a waste of resources to do that (and requires more verbose code), since we can easily check whether the browser is RGBA-capable, almost as easily [...]
UPDATE: New version First of all, happy Valentine’s day for yersterday. This is the second part of my “Using CSS3 today” series. This article discusses current RGBA browser support and ways to use RGBA backgrounds in non-supporting browsers. Bonus gift: A PHP script of mine that creates fallback 1-pixel images on the fly that allow [...]
