Light

The third factor is light. If you are in a dark room with no light, can you see the colour of the objects? The answer is obvious.

As already explained, in order for our eyes to perceive the colour of an object, the object must first reflect the corresponding radiation. Now, without radiation (without light), the object cannot do this. That is why we cannot see colours in the dark.

Do we need any kind of light to see the "real" colours of an object? In fact, we need a natural white light, such as that coming from the sun, to best perceive the colours.

There are many light sources that have a different colour temperature, which can influence the way we see colours.

For example: sunlight is not the same as the light from a lamp.

One reddish Colour has a temperature of 1000 Kelvin. 10000 Kelvin corresponds to a bluish Light. Daylightwhich is neutral, has a colour temperature of 5000 Kelvin.

This difference in how we see colours depending on their temperature is known as the metamerism effect.

We conclude this article by stating that capturing and perceiving colours is not an easy subject and that many factors need to be taken into account in order to achieve an optimal and satisfactory result.

The good news is that today there are devices that are specially equipped to circumvent these factors. Your printolino-team ensures that at least the Colours on the screen and the printed colours match and you get your picture in the most natural colour.
