I'm not Blake but I actually can't answer that question. I'd have to ask you what lake and what sky. I've stored some notion of color values for ex. a "stormy" sky and could probably compare that to the color value I have stored for the lake near my childhood home.

The abstract concepts of "sky" and "lake" don't have any color to me though. If you asked me to imagine a plane flying through the sky, the sky wouldn't have a color.
