Week 2 Color: Physics and Perception

Assignment 2: Photograph Color Wheel

For this assignment I started with a CMYK color wheel I found online. Easy enough to find, just Google image "CMYK color wheel" and it was the first result. I used this color wheel as a reference guide for the colors I would search for. I started at the top with red, searching for the most saturated red image I could find using Google images; using "Red color" as the search term. I did this for each color in my wheel using the names: Red; Orange; Yellow; Chartreuse; Green; Spring Green; Cyan; Blue; Azure; Violet; Magenta and Rose. Searching for the hues with higher white values, I would simply search with "Light" as a prefix to the color name. I selected the images I would use and saved them in corresponding folders I would be able to quickly reference when putting the wheel together. For the color strips I used a the google image search options to choose the color box cyan but search for "Red", and then choose the color box red and searched for "Cyan". I used this same technique for yellow to blue and then green to magenta. I had the same saving conventions as before, for quicker reference later.

When I had collected all of the images I wanted, I opened up a new image in Gimp. I created a layer for each color I was going to put in my wheel. I took out my first image, with the highly saturated red and put it at the top of my wheel. I cut out the second and third images and placed them vertically, slightly overlapping the bottom of the previous image. I did this the same way for each color layer respectively. When I was done cutting and pasting the images I went through each layer and set the rotation point where the center of the wheel would be. I rotated each vertical color bar I had created to their corresponding location along the color wheel and the color wheel was finished.
For the color strips I used the same technique of cutting pieces out of original images and pasting them overlapping each other along the strip.
