Powerpiont help (changing existing font colour)

[Noni Juice]

Hi there,

I have a lot of slides to print out, however Im almost out of black ink (have a full cart of colour tho)

How can I change the colour of all the text in the slides?

So far I have to select the text and then change, its very tedious and long, anything else?

Thanks for the help guys,

Now I have a problem though, some of the files are PDF files, how do I change the text colour of those
