Color Validation about wasp

[tuantr10]

Hi @devinmatte , may I work on this? I have never contributed to any other repositories rather than my own.
For the flow: I will limit the input value to 6-digits-length hex values.
I have 2 questions:

• Should we also allow hex values with the length of 3?
• Will empty input work with these 2 fields (theme_color, background_color)?

@tuantr10 Absolutely! I would love for someone to contribute.
Limiting to 6 values is perfect. If you want to allow 3 digit hexes that's fine, but I don't feel it required.
As for allowing empty input, look at the other methods that accept empty input, and set a default. I think #FFF should be the default value.

Thanks @devinmatte. I will create a PR when I finish.
