i would give it a couple of times passing stool and dont eat those candies if it returns to normal color then that very most likely is the culprit

I agree with Heather. Stay off the candies for a few days and see how it goes. Clay-coloured stools are certainly a sign of potential liver or gall-bladder disease, so shouldn't be ignored if they persist. However, we all produce odd coloured stools once in a while, so I don't think you need to worry if it clears up in the next week.

Change of diet can change stool consistency and colour. My dad got a dark purplish coloured stool after eating beetroot. You can also get dark stools after eating iron rich vegetables such as lettuce. Maybe you didn't absorb these candies well and that's why they the remnants of them showed up in your stools. Try putting meat back in your diet and avoid the sweets you were eating to see if your stools go back to brown again. Perhaps reduce the fibrous fruit a bit too. Maybe you are eating too much of it, You do say you are eating lots of fibrous fruit.

I put my money on Sweeteners being the culprit inside the candies. Sweeteners in large quantities are known to cause stomach upset, if the contents of your gut it moved through the system faster it can come out more loose and mustard looking.
