Beautiful magenta sky over Lake Crabtree. I made this 15 second exposure about twenty minutes past sunset tonight (just before the park gates closed!).
I found the reference to "Sky Magenta" from Wikipedia: This color was one of the colors in the set of Venus Paradise colored pencils, a popular brand of colored pencils in the 1950s. This color was sampled directly from the image of the actual colored pencil in a picture of a set of Venus colored pencils for sale on eBay. This color is also called medium lavender.
The sunset colors were deepened by layering three Cokin filters on the lens:
P123S - Gradual Blue B2 Soft
P121M - Gradual Neutral Gray Medium (ND4)
P197 - Sunset 1
Used Lightroom to process the RAW to JPG and cropped to a 4x5 aspect ratio.
