颜色 Colours

Hi everyone,

Everyone knows colours – at school we learn that light is split up into its colours by a prism.

just like a rainbow when it rains.

But when buying coloured ink for a computer printer,they use special colours.

Cyan ( blue)          Magenta  ( like purple )      Yellow       and black.

When you put a thermometer into each colour,you find that it gets hottest below the red = heat is infrared  (infra = below), whereas there are invisible rays above the purple (violet) called ultra violet. (ultra means above).

When buying paint,the shop will write the colour in a digital format,because there are so many shades of each colour, and they can be light colours,or dark colours.

Look around for special colours – pink ,brown, grey-

There are Primary colours with lights -mixing the three primary colours can make any colour.

bye now,

Peter
