Experimenting with light sources

Experiment number 2:

09 Experimenting with light sources

For a better understanding of the way lighting affects colour, I decided to use colourful textiles and objects for my experiment. I also decided to reproduced the experiment with other colourful elements in order to confirmed the results of the colour perception under different light sources.

Regarding experiment 1:

The daylight colour compact fluorescent light offers a bright, true and vibrant colour vision of the blue but it has a tendance to fade the red colour which is present in the shoes, as well as in the flower pattern of the dress. The warm white colour compact fluorescent light source results in the opposite effect. The blue, in that second case, is faded, detracted by the warm light but the red is vibrant.

The LED light gives a good compromise between the vision of the blue and the red. Their vibrancy is slightly less than the previous cases. Also, the perception of the white seems bluish, probably due the cool light colour of this LED.

With the halogen light (incandescent light bulb), the perception of all these colour seems right and balanced. I would like to reattempt this exercise with a change of the focal point of the light. Probably the blue will appear less vibrant due to the warmish light.

Regarding experiment 2:

The daylight compact fluorescent light results in a vibrant perception of the colours. The shapes of the elements and their motifs are well defined when compared with the other light sources results.

With the warm white compact fluorescent light , the warm colour orange is well enhanced and the blue is dull. The pink and the green also appear with a slight touch of orange.

The halogen light has a also a poor blue rendering. The bag’s fabric results in a glare from the direct light.

In relation to the LED, the colour rendering is well vibrant where the light is focused on, but shades and tone changes appears towards the outlines.

For this scenario, the daylight compact fluorescent light gives the better result regarding the perception of the colours.
