# Selecting Semantically-Resonant Colors for Data Visualization Semantically-resonant color assignments (such as mapping "ocean" to "blue") are useful in categorical visualizations, and can facilitate value lookup and comparisons. This repository contains C# code that assigns a set of categorical concept names to semantically-resonant colors. The algorithm makes use of images to determine frequent and discirminative colors for each concept name. It uses Google Image Search to query for relevant images. Project page: [link](http://vis.stanford.edu/papers/semantically-resonant-colors) Main file: SemanticColors.sln ## Dependencies * [c3_data.json] (https://github.com/StanfordHCI/c3/tree/master/data/xkcd) - Needed for computing color name distances. Download to some place on your computer * [Google CustomSearch C# Library v1.3.0] (https://code.google.com/p/google-api-dotnet-client/wiki/APIs#CustomSearch_API) - Add/Update the reference to Google.Apis.dll and Google.Apis.Customsearch.v1.dll to Engine.csproj * You'll also need to sign up for an API key and set up a [CustomSearch engine](http://www.google.com/cse/all). There's a daily query limit for the free option. * Create a new search engine with an initial site url. * Then edit the engine, and remove the site from **Sites to search**. Change the selected search option to **Search the entire web but emphasize included sites**. * Enable **Image Search**. The code has been tested on Windows 7. ## Usage Usage: SemanticColors [inFile] [outFile] [paramFile] [renderDir] * inFile - file with list of categories to assign colors. See sampleCategories.csv for an example * outFile - output file where color assignments are saved * paramFile - config file. See sampleParams.txt for an example where * imageDir - is where images of concept names will be saved * cacheDir - is where computed histograms will be saved and re-used * jsonFile - is the location of the c3_data.json file * apiKey - is your Google CustomSearch API key * cx - is your Google CustomSearch engine id * renderDir (optional)- If included, images of the color assignments and affinity scores for each category are saved in this directory.
