Here’s an image taken on a full-spectrum Pentax K-3 with a 550nm filter on the lens. The resulting raw was converted with Darktable (channel swap RB split G and some manipulations in the color zones module) which resulted in blue skies and orange vegetation. I used Gimp to pull the vegetation more towards a Kodak Aerochrome red using the Hue/Saturation tool to change hue on the yellow shades in the image more towards the red.
