That water has a...red tint?

It's water all right. You near the oasis, reaching out and touching the trunk of the palm tree just to be certain it's real, then you scan the pool of water. It's a decent sized pool, probably five feet in width, and fairly deep in the middle. You drop to your knees and cup your hands to drink, but as you pull the water toward your mouth, you realize that the water in your hands seems to have a red tint to it.
You look to the pool, then back to the water in your hands, your mind immediately telling you what might be diluted in that water to make it red.
You shake your head, scattering the idea. Blood? What were the chances that blood was mixed with the water?
Not very good, you decide. Most likely, you're just seeing things, the bright light and lack of water getting to you. You lift your hands and pour the water into your mouth, savoring it as it rolls down your throat. As you empty your hands, your mouth begins to water, wanting more. You get two more handfuls and drink again, then again.
Finally satiated for the time being, you sit back on your heels, content for the moment to relax here and rest.
