Yeast colour

[LeffeFan]

Just done a brand new Coopers Mexican with malt/dextrin and bottled water. All went great until I opened the yeast sachet. I noticed about 30% ish were brown not white.

Something I've not noticed before. Is this normal? Will my brew be ok?

I pitched it anyway as I guess leaving till Monday wouldn't be too good for it and it was bang on 24 degrees and spot on OG.

I assume this is because the Mexican Cervesa yeast is a mixture of ale and lager yeast.
