The 'all or nothing' power of three primaries can take us from 3 to 8. Before we add more between those two extremes, let's review how C, M, and Y add up, pure and simple . . .
All or nothing. Full or empty. 100% or zero. As much as possible, or none at all. There are more ways to say it, but the message is simply this:
The eight Corner Colours in the BreakThroughColour system are based on
the full presence or complete absence of three 'primary' ingredients:
Because they can't be distilled down to any simpler source, and are the foundation of every Hue, Tint, Shade, and Tone in the BTC collection, C, M, and Y are like our periodic trio of elements.
They are true Hues on their own, and they also pair up to become the other three, R, G, and B. And as opposite as 'nothing' is to 'all,' the Hues are bookended by W and K (White and Black).
With or without Cyan, with or without Magenta, with or without Yellow, here's another look at how our three element primaries can add up to become greater than the sum of their parts:
The full Colour Square identifying each of the Colour Basics Corner Cards clearly shows how each of these Corner Colours is all, full, 100%, as much as possible:
The 3-digit Colour Code on each of the BreakThroughColour Corner Cards is also a clue to each colour's 'all or nothing' mix of Cyan, Magenta, and Yellow, in that order. Compare the codes here with the grid of colour block sums above and you'll see how the minimum and maximum values (the none of '0' and the full of '5') correlate to each of the eight possible CMY combos.
So, how do we get from these eight Corner Colours to all the other colours in the Colour Basics deck? What's up with the Colour Squares that show the colours as halfs, or halfs of halfs?
And what about the BTC Colour Codes that vary all those 'all or nothing' Corner Colours with 'a little, some, more, and lots more' by adding 1s, 2s, 3s, and 4s?
To get from 3 to 8, we gave each of our element primary colours two versions: all or nothing. Two versions of Cyan, two versions of Magenta, and two versions of Yellow.
To connect every Corner with every other corner and have them meet halfway, we'll need to add a halfway version: empty, half, and full.
And if we add 1s, 2s, 3s, and 4s as steps between our 0s and 5s, we'll give our original three a full scale of six versions: none, a little, some, more than half, almost full, and full.
There's gonna be more math. But there's also gonna be pizza...
