What can I do with cracked sidewalk and patio?

I don't have the money to have all my old concrete sidewalk and patio broken up, removed and re poured. Sections were done at different times and some are even different types of concrete. There are cracked areas too. I'm just looking for a short term fix to make it look more uniform. I've heard of cracked patios with thyme or moss in between. But what I found are instructions to start from scratch with stepping stones and sand and dirt etc. Can I do this idea without removing everything? Are there any ideas for how to make the different colors look the same? Paint? Cleaning? Stencils? Thanks for your help!
