Motivation and context

Types of changes

Patch (bug fixes, typos, mistakes; non-breaking change which fixes an issue)

Minor (add a new token, changing a value, deprecating a token; non-breaking change which adds functionality)

Major (deleting a token, changing token value type, renaming a token by deprecating the old one; fix or feature that would cause existing functionality to change)

Checklist:

I have signed the [Adobe Open Source CLA](https://opensource.adobe.com/cla.html).

I updated the token in all applicable sets. This applies if updating, adding, or deleting a token that has data across different sets (for example, if the value differs across color themes.)

@larz0 This would be the first color token with the word 'color' in it. Notice: This line in the json file is not the spectrum-tokens name, but the name for the token in figma and the variables. @nabuhasan and @lynnhao might know more...

Please put the spectrum-tokens name into the nested spectrum-tokens object, e.g. here: https://github.com/adobe/spectrum-tokens-studio-data/pull/168/files#diff-1b6a253c366c334e1436d57bc36dc0e6083a2300ce2c823b8a68c1cca5ef4017L278

In Spectrum Tokens we would want the word color to be in there because it's the property it's changing. I guess we could use fill-color or background-color but color alone is fine. As far as what the name should be in Tokens Studio data, that's up to @nabuhasan and @lynnhao to approve or ask to change.
