Albers.io is an interactive web workspace made for doing exercises from Josef Albers' book "The Interaction of Color." The project seeks to bring some elements of the book into a digital environment, in order to make the work more easily accessible, and to make learners aware of differences between color on screens and color in print.
##The Book
In his book, Albers recommends that readers acquire a wide range of colored paper by cutting up magazines. Readers then use this palette of colored paper to demonstrate the relative properties of color by completing various excercises.
##The Workspace
The albers.io workspace provides a palette of colors scraped from tumblr, and a canvas on which exercises are conducted. Click any color on the color palette to create a rectangle of that color in the canvas environment. Click and drag to move rectangles; ctrl+click and drag to resize rectangles, and shift+click and drag to rotate rectangles. Rectangles inserted later are drawn above rectangles inserted earlier.
##Quick Setup
To setup and run the current albers.io workspace, execute the following commands:
git clone https://github.com/sakekasi/albers-io.git
cd albers-io
python -m SimpleHTTPServer
The workspace should be running at localhost:8000
##The Implementation
To get a list of colors, utils/colorgenerator.js uses the dominant-color library to get the dominant color of an image and outputs a list of these colors to colors.json.
The workspace is written using React, with the canvas environment written as a custom component using the Easel-JS canvas drawing library.
##Building
To build albers.io, execute the following from the project directory:
npm install
gulp build_browser
##Generating Colors for the Palette
In order to scrape colors from a directory of images, edit the dirName variable in util/colorgenerator.js to point to a directory of PNG images that you would like to scrape. tumblr-photo-ripper.rb is useful for this task.
Running node colorgenerator.js should output the scraped colors to colors.json. Copy this file to the root directory of the project to have the workspace use the scraped colors in its palette.
