Many hostas will emerge in the spring with a certain color scheme, and gradually the color changes during the season. The yellow color on many will fade to a nice light creamy color... Sometimes, if they are planted in a lot of sun, this transition could happen faster...

Buff

the warmer the spring.. the faster the fade ...

have you had an above normal warm spring???

or are you just focusing more on your hosta?
