Mixing pools of Light

The significance of light transmitting colour to human eye was vividly demonstrated to me in my early teens, at a children's conference in London.   The guest speaker projected red and green then blue onto a screen on the platform of a darkened Westminster Hall.

Pigment, light reversed

        With amazement, I first saw yellow created by the addition of green on red, then magenta and cyan appeared with the inclusion of blue.   In the centre of the three pools of merging colours, was a brilliant white.   I was later to experience the same phenomenon on a computer screen when experimenting with my first "BBC B" computer, and logically created the reverse, to reveal the primary colours of pigment.   The illustrations above, along with the other images in these pages, were created using an ethernet linked dual-platform, of a StrongARM Risc PC (OS 4.2) and Microsoft PC (OS Win98) with attached scanner and colour printer.
