how do i make my fondant gray, similar to the color of stone?
i remember a while back i thought mixing white + black would give me gray, but that was an epic fail and i had army green! (???)
i dont have cake supply stores nearby other than michaels and ac moore. not sure that they sell gray coloring... does anyone know?

what brand if fondant? Every company has their own color mixing chart

It might also depend on your brand of food colour. I mix Sugarflair Extra Black into white fondant, I have used a few brands, and it works fine.

I usually take a tiny bit of black fondant and mix with my white, no matter the brand it make a pretty grey for me. even with modeling chocolate grey. It only takes a little bit whether it is black fondant or you are using the paste or gel black and coloring the white. hth

for this cake, im usung wilton. i think i used wilton or satin ice white and mixed in duff's black when i had the army green issue. i havent tried using the icing color.... so i think i will do that first. if that doesnt work i can use the silver color mist spray- it will be close enough .i dont think my toddler aged niece will mind if its a little shinier than stone usually is =)
thanks everyone!
