Ndebele




































The Ndebele houses are painted by women who have been taught the techniques as part of their girlhood initiations. Originally, the designs, painted in mud and naturally occurring oxides, were comparatively muted. 
Over time, the colours and shape became a key aspect in the overall design. In the late 1960s, the new style was evident. What was once a finger-painted creation was now created using bundled twigs with feathers as brushes. The walls are still originally whitewashed, but the outlines and colours have significantly changed. The patterns and symbols can be seen today with a rich black outline and a vivid colour inside. 
There are five main colours represented: red and dark red, yellow to gold, a sky blue, green, and sometimes pink. The colours give an intensified symbolic meaning to the Ndebele. They can mean status or power of the home's owners, offer prayer, announce a marriage in the home, or can represent a current protest. The paintings express an abstract meaning with no real reference to any specific characteristic of their homes. This is the most direct way to show their individual expression to the people outside their far distinct family, showing of the talent and the taste of the mother. The colour white is always used as the background because it makes the bright patterns stand out more.

peacock mantis shrimp












This extraordinary beastie is a marvel to see but also has super natural vision
it views the world in 11 or 12 primary colors, as opposed humans who only see 3
 making it possible for them to perceive both polarized light and hyperspectral color vision
Not to mention they possess super strength in their claws, that can break aquarium glass
During mating rituals, mantis shrimp actively fluoresce, and the wavelength of this fluorescence matches the wavelengths detected by their eye pigments. Females are only fertile during certain phases of the tidal cycle; the ability to perceive the phase of the moon may therefore help prevent wasted mating efforts. It may also give mantis shrimp information about the size of the tide, which is important for species living in shallow water near the shore.
