Closure Compiler fails with duplicate member "cool" error

[taschukMax]

When trying to use Closure Compiler it fails with the following error:

Class or object literal contains duplicate member "cool". In non-strict code, the last duplicate will overwrite the others. 16739| "cool":[{"index":0,"rgb":[0,255,255]},{"index":1,"rgb":[255,0,255]}]

When reviewing non minified version of plotly it does contain 2 "cool" keys
