The pages mentioned in the overview below are "off-topic" for the site "The early adventures in Spaceflight", are kaleidoscopic in nature and somewhat notebook like. Some pages are even far from finished. Therefore these pages are kept somewhat concealed. They hitchhike with this site as stowaways, so to speak.
However I have started to create these pages because it helps me, and to some extent, forces me, to organize the knowledge I have gained on a wide variety of topics.
So it is to be expected that more pages on other topics will follow which might be of interest to others.
The knowledge itself has been borrowed from other sources. I just have put some effort in the presentation to provide insight and overview.
1
RGB (Red Green Blue) Color Cube
All colors of the RGB Color Cube are shown with a color spacing of 11 (HEX).
The shading of the colors can be organized along various axis.
In this presentation the shading is organized in parallel planes of the cube along the red-axis, the green axis, the blue axis and all the six diagonal planes.
Furthermore is shown which colors of the RGB cube constitute the rainbow color sequence.
2
The Color Cone
In the Color Cone the colors are not arranged along the axis of Red, Blue and Green but by color (Hue), color intensity (Saturation) and by how much white or black has been mixed into the color (Luminance). This arrangement is more intuitive then that of the RGB cube model.
