Stefand, I tried to look up your two roses, I don't see where you are from, if you live in a warm climate with lots of sunlight, then roses fade very quickly. I looks like Seagull is a white single rose, and Mermaid has a larger pale yellow bloom with floppy petals. Put in a search for Mermaid, and look at Baby Mermaid (also known as Happenstance), there are a few others, most look like they are white. It's harder to tell between those other Mermaid roses, lots of people grow the Mermaid roses, look under the tab "Garden" at the top of each rose entry and use the pulldown menus to find people who have listed that rose. Some people with be happy to take your questions. Also look at other rose databases, Rogers Roses, Just Our Roses (might be Australian based ?).
