Switch Comp default color is not 'default'

[TallOrderDev]

• [ x] This is not a v0.x issue.
• [ x] I have searched the issues of this repository and believe that this is not a duplicate.

Expected Behavior 🤔

The docs indicate that this is NOT the correct behavior, but I think it might be off.

The default value for color on the Switch comp is 'secondary', I would expect it to be 'default'.

Current Behavior 😯

currently if you do not provide a color to the api for color, it will default to 'secondary' and not 'default'. This might be the correct behaviour, but I'd infer default would be default.

Context 🔦

Not sure what the correct is, just looking for clarity, and I couldn't find an issue that covered this, so I thought I'd open one before we get to far into 1.0
