In this CAMI meeting, Aren and Mark brought some tools for us to explore colors and play around with one way that humans have developed to quantify colors.
Find the color that describes how you feel right now, or
Find your favorite color
Click on the image (or the link above) and play around with the slider.
Next, we shared some stories and discoveries.
Next we made observations looking at this image:
Here were some of the things we noticed and wondered:
What we noticed
When they’re lined up, things are different than when they’re in different positions.
This yellow I find amazing that it’s saturated red and green. I find it amazing that that’s yellow.
“Saturated” – The dot is all the way over for the red and green and the number says +255. The blue is 0.
So one end is the highest and the other end is the lack of. A lot of red and a lot of green give you yellow.
Different from what I learned about colors – where blue and yellow made green
I started by looking at the arrangements of the dots
The similarities in the shapes on the dots in triangles may be related to the color
The two green ones are very similar triangles
Looking at patterns in the dots. I noticed that the two greens have the same shape of dots. The two purples have the same shape of dots – triangles that are differently stretched, but the greens are scooched over.
What I would call pink has the second highest blue value – if I wanted to arrange these in order of blueness , just based on the colors, that is not what I would have at number 2
The light green has more green than the deeper green (225 compared to 150)
What we wondered:
If I tried to put these in order of how blue they are, what would that order be?
What would happen if we moved the blue level in the pink color to the right? Would it make purple?
Which number combination would make white? – I think about the rules for colors. If you mix all the colors in paint, you get black, but if you mix all the colors in light, you get white.
Are there some fundamental ratios that this is built off of?
If we play with numbers, if we play with ratios what happens as we do things like double all the values? When will it stretch? When will it result in a similar shape?
What could we do with the numbers that would keep the same shape of the dots?
Next we took some time on our own to explore this RGB COLOR MODEL. The task was to play around with the slider and keep track of any questions that came up for us as we played.
Take some time and play around with the RGB model yourself. You can follow your own curiosity or start by investigating one of our wonderings.
Here are some of the ideas and questions that came up for folks:
What else did you notice and wonder?
I found white and black. From the beginning I was arranging the sliders vertically and found grey. With all the sliders to the left it made black and all the sliders on the right made white, with shades of grey in between them. – Linda
The thing I was testing that I think was not right, but was interesting to me. I would make a triangle and see what happened. If you slide the sliders without passing a dot that would disrupt the triangle, I thought maybe it stayed within one color family, but then I found a counter example. – Amy
There is something to maintaining the thing that has the most saturation. – Amy
As with many CAMI meetings, we ended with more questions than we started with. Aren and Mark left us with some tools to explore our questions and a final thought on colors:
