Why the error?

Option 1 | Feed Rules
If you have your colors written in the titles, than you can use Google merchant feed rules.
Login to Google Merchant and navigate to Products > Feeds > click on feed name > (Tab) Feed Rules
In this section click on Add Target Attribute and choose color

Click on the radio button next to Create a value based on criteria in a feed field:
Than select title from the select field and contains from the select operator, add the color in the text field. For example blue
Set the value for ‘color’ to, add the value of the color, for example blue.
Click on continue.
If you have more colors to add, click on the +condition and repeat the process.
