I'm not sure on your egg colours but I did have a Sussex cross that laid very light coloured eggs. I don't have experience with leghorns, sorry.
About the wing clipping, it's fine to clip a wing. Only do one though it's to unbalance them in flight. I've had to clip before to stop escaping. Here is an article all about it https://www.backyardchickens.com/a/how-to-clip-trim-the-wings-of-your-chicken-to-prevent-flight
Good luck with your escaping birds
