Raisins are brown because they are grapes that have been dried out in the sun. Usually, the "brown raisins" start out as purple grapes. The white ones turn a bit lighter brown, not the dark brown as most of us are accustomed to from SunMaid and such, so they start out purple. And then, the sun's rays heat and dry out the grapes, and they shrivel up, creating that pruny finish - like how your fingers are after they've been in water for a large amount of time. Just like our skin, grapes shrivel up when they dry out. Also, just like our skin, it loses it's color as it dries out. The vibrant purple grape is changed into a dark brown, shriveled up grape - thus creating a raisin! IN SUM: The sun's "heating/drying the grapes" process discolors the grapes.
Hope you found this useful. :) Best of wishes! Xx

What is the best theory for osmosis with grapes and raisins in salt and fresh water?
The best theory for osmosis in the context of grapes and raisins in salt and fresh water is the semi-permeable membrane theory. When grapes are placed in fresh water, water enters the cells through osmosis, causing them to swell and become plump. Conversely, when raisins are placed in salt water, water moves out of the cells to balance the concentration of solutes, leading to the raisins shrinking and becoming wrinkled. This demonstrates the movement of water across a semi-permeable membrane in response to concentration gradients.
