Project 31 - analysing a colour

The question for this project is how can we change 3 colour qualities - hue, Brilliance and saturation of the photo during the actual filming?

hue -by using colour philters on the lens
Brilliance - as i did at project 30 - to vary the exposer
Saturation - as far as I understand, in real-time, there is no such an option.

Project 32: Primary colours

In this project we had to take photos of the 3 primary colours - red, yellow and blue in different exposers.

Red:
F/5.0

F/5.6

F/6.3

The avarge-exposed photo is the closes for the colour circle.

Yellow:
F/5.6

F/5.0

F/4.5

(Sorry for the subject, but this is so yellow!) I think that the under-exposed photo is the closes to the colour circle.

Blue:
F/5.0

F/5.6

F/6.3

I think that the over-expose photo is the closes to the colour circle.

I had 3 different answers to one question. I wonder if it always the case or i just picked the subjects like that. I think that the yellow in the colour circle is very bright and the blue is quite dark so the results I got did match it.

And if we're dealing with colour, their is a photo which I like very much and it's all red... The photo is from 1952 and it's been taken by Milton Greene which declared that he is 'a photographer of beautiful woman'. The photo is of the model Suzy Parker and for me is a total womanhood.
