DeltaE global now accessible.\n    \u003cscript src=\"bower_components/delta-e/dist/deltae.global.min.js\"\u003e\u003c/script\u003e\n\n    // Create two test LAB color objects to compare!\n    var color1 = {L: 36, A: 60, B: 41};\n    var color2 = {L: 100, A: 40, B: 90};\n    \n    // 1976 formula\n    console.log(DeltaE.getDeltaE76(color1, color2));\n    \n    // 1994 formula\n    console.log(DeltaE.getDeltaE94(color1, color2));\n    \n    // 2000 formula\n    console.log(DeltaE.getDeltaE00(color1, color2));\n\n## Tests\n\nA simple Mocha test is setup to test the accuracy of each dE algorithm, for both\nnpm and Bower versions.\n\n    $ cd tests/\n    $ mocha main.js\n\n## Gulp Tasks\n\n### build\n\nBuilds both the Bower and npm version from source.\n\n    $ gulp build\n\n### jsdoc\n\nGenerates full documentation in the /jsdoc/ folder.\n\n    $ gulp jsdoc\n\n## Licensing\n\nThis is Unlicensed.
