All in all

I have two close friends who both are artists.

The other one is red-green color blind. He is an illustrator and before he started working with Painter program he bought colors by their names (red-something and green-something) and told me how he used to place red and green colors to the opposite sides of his watercolor palett.
He can not see the difference, only the darkness-lightness values between anything concerning these color combinations. As he told me, the way he sees these missing colors are something between brown or gray. Even so this does not affect his art:

The other artist friend of mine has a glaucoma. He is trying to paint as much as he can before he becomes blind. Glaucoma cannot be cured. He tried the medication, but it did not help so now he is facing an operation in which they try to diminsh the pressure in his eye:

About Group 1's assignments:

Visual Attention we did babdly: we just chose of the six topics two to each, and it was a bad thing since they all are related to each other. It was clearly a textbook thing and we could have got further – maybe – together.

With the other assigment Local Environment it was easier to divide who does what.
My concern was the mapping in the way the client wanted: as a blanket. The client wants two colors: green and red. I had tried all color combinations as the Global Environment group had done: from red to yellow to green with through yellow.
I knew there has to be a more simple way of doing it: there cannot be more than two colors. To keep things simple for the user: KISS-rule. So I talked the members of our group as well as the client to have the other color black. What is the good color then?

I understand the point red: alert!!! But I put black first. Yes, a negative color, but maybe we change into some other by showing a point, by making see there is as something else?

Why black is worst is because painters for some time have used to represent bad. There are examples from Soviet posters (Potjmekin) or Picasso's poster where the pigeon flies over the black guns with the green olive leave in  its mouth. These are the colors that we understand in our culture, also green is the color to which a human vision is most perceptive of.

I could of course wonder largelly of all the mathemaical equations about color, but since I'm not in to that I just wish you all

Merry Christmas and thank you all especially Markku for the great course

See you next year
