Colours of felt pen ink separated. The Image on the right is a simple inversion. The water soluble ink is in two colours: cyan and magenta. See the comments for details.
My daughters science lesson on-line.
The pen with water soluble "black" ink is labelled MICKY MOUSE from Disney. A radial chomatogram made with water as the solvent separates two colours.
Cropping a section of the central image (top right). Cropping rectangular panels from that image and scaling gives the figure second from bottom. Overlaying the central portions of those panels at 50% each gives black. The two inks have complimentary colours, cyan and magenta.
Micky mouse knew what he was doing.
Tiny orange flowers in a blue plastic bowl. The inversion is on the right reversing the colours. The inversion is not perfect - to make it perfect requires using selected dyes that match the RGB detectors in the retina. Single image in two parts - both parts are required to confirm that the colours are complimentary.

Inverting the yellow/magenta transmission image(on the right) shows the complimentary green and blue colours that are seen in reflection (here .... www.flickr.com/photos/jacobs_ian/9892617515/).

Cellophane sweet wrappers sometimes have interesting properties. This one looks green and blue in reflection (due to thin film interference) and shows the complimentary colours (yellow and magenta) in transmission as you would expect. Inverting the yellow/magenta image (here ...http://www.flickr.com/photos/jacobs_ian/9892620755/) gives the green'blue complimentary colours.
