Sorry for the late response.
shopify team says that your theme is not shopify compatible therefore this error comes… they say if you change theme the issue is solved
>>> Please try to activate another Shopify theme to check this function, our theme has 100% compatible with Shopify. You need to type the right color name to solve this problem. You can refer the color name here https://www.quackit.com/css/css_color_codes.cfm
Regarding the next issue, I saw you’re using the outdated version, please update to the latest version. The problem will be solved.
