Can someone edit an effect for me?

I’d like to have an additional color added to Custom Sunrise; Effect ID -MO8liV7Dy1JZC5l7nfQ so that there’s a total of 4. Is this possible?

Not even a “Welcome to the Forum” message after 4 days. Huh.
I’d do this myself, but code doesn’t agree with my autistic brain. Any help, direction or anything would be appreciated.
