ABSORB light

A surface will absorb some or all of the different light waves and reflect some or none.

Consider different surfaces (reflective / shiny, or matt) when looking at different effects of lighting at different times of the day.

Also consider coloured glass, coloured lights, sunlight, and moonlight.

All these factors in a room will create different colours and thus emotional responses.

What happens when you have a coloured transparent material like a lampshade, stained glass, or a sheer curtain to the surrounding colours?

lets experiment -

If you shine a light through green and red cellophane it will create a yellow light. There is no blue primary light about.

We see the yellow and the other colours are absorbed.

so if you use a yellow light fitting it will create yellow light - the other colours are absorbed.

enjoy the colours reflected under the sunlight!

Shining a yellow light through blue will be black!

The green and red are absorbed and the blue is not in the equation - yellow light doesn't contain blue light

 black walls absorb all the colours nothing is reflected unless it is a shiny surface and some white light is reflected.


Shining a yellow light through green cellophane will be green

The  red is absorbed, the green goes through and the blue is not in the equation - yellow light doesn't contain blue light

Shining a yellow light through red cellophane will be red

The green is absorbed, the red goes through and the blue is not in the equation - yellow light doesn't contain blue light
