Deprecated npm package ember-chroma-shim

[mattwr18]

when getting set up with the project locally, and running yarn install, it throws this error

error An unexpected error occurred: "https://registry.yarnpkg.com/ember-chroma-shim/-/ember-chroma-shim-1.0.2.tgz: Request failed \"404 Not Found\"".

Looking into it a little further shows that this package is no longer being published, so we need to find an alternative. https://npm.taobao.org/package/ember-chroma-shim

Expected Behavior

yarn install should find and install all npm packages necessary to run the project.

Current Behavior

it errors out every time.

Possible Solution

check if this is even needed any longer. Maybe chroma.js has been updated to provide support for ES6....
Looking into it a bit more shows this issue that says it is now ES6 compatible gka/chroma.js#138 (comment)

Steps to Reproduce

1. cd frontend
2. yarn install
3. 😢
