Sheep and wolf spawn eggs look confusingly similar

Very closely relates to MC-242097

The bug

The colors used for the wolf spawn egg very closely reesemble that of the sheep spawn egg, only slightly darker, which can lead (and has led) to confusion. The results of this may pose disastrous if a wolf is spawned among sheep the player would not like killed.

How to reproduce

Simply obtain one of each and compare.

Expected results

The colors used by each would be considerably different as to allow for easy distinguishing of them at first glance.

Actual results

Distinguishing them takes a bit more effort than normal and can easily lead to confusion in certain cases, especially in a rush.

How to fix

Either one or both spawn eggs should have their colors updated to stand out from each other more.
