We have an old fireplace with an open fire. The surround and hearth are tiled in these types of tiles (the lighter coloured ones) -

We want to update it a little, but not rip it out. I was wondering about colouring some of our tiles darker (like in the picture) just to give it a less solid and boring look.Any suggestions about whether these type of tiles can be stained/coloured in some way. I know that there is tile paint on the market, but presumably that would remove the "mottled" effect entirely. I also have to make sure they are suitable for a fireplace too.
Many thanks in advance for any suggestions.
