Welcome to the Bolt, countryboy.

Check the web page to PPG and find out their color code for that color is 11807 or check this color chart from another site to see the color.

There appears to be two turquoise colors with the designation 710A on the color sheet. Hopefully one should be closer to yours than the other.

Hope this helps and hope your new year is a good one.
