Wouldn’t it be cool if sunsets like these existed?

You can also try my Channel Colorizer to put some color into your own images.

Here is a basic example for making a search for “banana”-themes from Kuler in Actionscript 3. To use it you need the ColorMunch class an your own Kuler API key. There are some more examples in the ColorMunch wiki, but you’ll find the most useful information in the documentation provided in the ColorMunch zip-package.

• Register for a Kuler API key
• Download the ColorMunch class and extract it to your fla-folder.

Example of using Adobe Kuler in Flash AS3 via the ColorMunch class:

Adobe Kuler gives the coloring an extra dimension. You can search for whatever comes to your mind: bananas, fire, happiness, an author or a specific color. Just keep in mind that you have to be a little bit patient with the search times, since the kuler-servers seems to be a bit overloaded.

The demo features a couple of really cool techniques:

• The Pixel Bender filter running live with webcam support.
• Coloring themes using Adobe Kuler via the ColorMunch AS3 class by Ben Kanizay
• Asynchronous saving of JPEG-files in Flash based on libjpeg using the Alchemy JPEG-encoder AS3 class by Mateusz Małczak

Go ahead and make some cool images and feel free to post some comments about it!

I also added so that the normalization works when color values are too low, not only when they are too high, as in the previous version.

After a bit of testing I realized that I mostly wanted to have resuts that did have some normalization, but not full, since this could make the colors a bit dull. To solve this I added the option to set in percent how much normalization to use in the filter, and the result was great. Setting the normalization to 50% preserves both a lot of details and some of the sharp colors.

I had an idea for a (probably) very cool graphic effect for Flash using colorized dots. My intention was to make it so it could be used for images, animations, videos or whatever. To do this effect I realized that I needed a way to change colors of the graphics in an easy and precise way. Since I’ve worked a lot with the Pixel Bender Toolkit lately, it came natural to make a pixel bender filter for this task.

The filter is made to change each original RGB channel of an image into a different color, defined by the user. The filter also has support for the transparency in the alpha channel (RGBA format). However, it is a rather abstract thing to understand the effects of changing the transparency in to color or vice versa, so I will leave it for you to experiment with if you really need it.

The above image is filtered using the color transformation in the diagram. You can see how the colors differ from the original image to the right.

The filter can be used with two settings, balanced or unbalanced. The default setting is unbalanced which sets the channels to the specific colors exactly. This causes the the colors to go outside the boundaries of the RGB color space when the colors get to intense. The effect is that the colors get cut off at a specific point, when they can’t get anymore intense. The balanced setting corrects this and normalizes the color so that all details gets preserved and nothing is cutoff. This sounds good right? Well, the negative effect is that the colors no longer is the exact colors you specified and sometimes the colors get very dull or desaturated. The filter is now updated and the colors are now correct all the time.

Here is an example of the two sides of the balancing with an rather extreme color setting. The picture on the left shows the original image. The picture in the middle has an unbalanced color setting. Here you can see that the image matches the colors but some intense colors in the flower gets too intense and loses detail. When turning on the balancing in the right picture, the detail comes back, but the colors no longer match the color setting. Read about the updated normalization.

The filter can be used in a lot of ways for a lot of purposes and I bet you can find more uses of it:

• Changing each channel to a different color
• Mapping the colors to a specific color theme or scheme
• Changing the image to black and white (or decolorize/desaturate)
• Changing the image to black and white with a specific color tone or tint (sepia for example)
• Creating a color weighted black and white image
• Colorizing an image to a specific RGB color
• Extracting a specific color channel

The filter is primarily made for use with Flash, but works fine with Photoshop as well. To use it in Photoshop you need to install the Pixel Bender plugin for Photoshop CS4 and copy the Kernel file to the Pixel Bender folder of Photoshop. If you want to use it in Flash or Flex, Lee Brimelow has made some good tutorials on how to get started with Pixel Bender and Flash.
