Eloise: Hello, and today is the first amazing post of Interview, Interview, Interview, I'm here with a top colour scientist- Cari H.
Cari: It's great to be here, thanks for inviting me!
Eloise: So what brought you to this subject Cari.H?
Cari: Well, I have always been interested in science and we had to do a project on Black and White at school, and I decided that this would be a good way to link my interests to the topic.
Eloise: What a great way to connect your hobbies with projects, so what interesting things have you for us today?
Cari: One of the most fascinating things to do with this is that you get different responses from different people. Asking an artist, you would get a response along the lines of "Both of them are not colours," but if you asked a scientist (not including me!) you should an answer based on physics- white is a colour but black isn't. It depends, though, whether the colours are generated as light or as pigment.
Eloise: So could you explain and describe this in further details for our fellow readers?
Cari:White light is the spectrum of seven colours mixed together. When our rods and cones are both stimulated at the same time, we see white.
Black is the absence of visible light.
Eloise: And you mentioned pigment? What about that?
Cari: White is the absence of pigment. In albino animals, they are that way because they have a genetic mutation, so they lack melanin (pigment in their skin)
Black is cyan, magenta and yellow pigment mixed together.
Eloise: Thank you very much for your time you spent with us today.
Cari: You are very welcome! My pleasure!
Eloise: Tomorrow we shall be discussing white light with Ms Lauren.D
Hi! I've done an interview as well! (Different subjects though)
