Color Coding Your Chart

 I love color coding. I got my first BIG commission for introducing a color-coded filing system to Boeing in the 1960s. It was for the 737. Don't blame me, it was only the files.

To move on, I have had a lifetime of experience with color - and coding - and color coding. 

Today I am applying the principles to 'Knitted Cables.'

Fortunately, the color wheel has more than 3 primary colors: Red, Blue, or Yellow.

We get to use secondary, or even tertiary colors.

To make it even more fun - we will distinguish between warm and cool colors. And light and dark colors! What a festive array!

Secondary colors are what you get when you mix two primary colors: Purple, green, or orange.

By now you may have noticed that some colors are easier to see if they are darker. For example, 'orange' has been made 'brown' so it can be seen easily.  (I have not shown yellow at all, except - see below) !

But, if I put any color within a black outline, it is seen much more quickly. Even white  will show up if it has a boundary of black - as in:

 

(Black on black defeats the purpose of the illustration)

Notice that yellow and black have the most contrast. That is because yellow is a warm color, while black, like white, is neutral. Grey without an outline, almost disappears from the page. Also, scientifically, black is either all colors or no colors, (I forget which) and white is the opposite, but black is dark and shows up well.

Typographers will use those features of colors to give their message an impact. But everyone enjoys color - as witnessed by movies and tv producers.

Given that yellow, and its neighbors, red and orange, are warm colors and appear to come forward if I am illustrating a stitch that comes forward I will use a warm color.

Likewise, a stitch that lies behind a stitch that comes forward gets grey, outlined in black. Because it is behind - and harder to see.

That takes care of 'knit' and 'purl' - but what if your cable is ' knit - knit' or 'purl knit' ? Or 'knit - purl - knit'?

That is when we use tertiary colors and values. 

Tertiary colors happen when you mix two secondary colors, or a secondary color and a primary color.

They will show up as 'lavender-blue' or 'red-violet'.

The Value is seen as the lightness or darkness of a color. Such as 'red' vs. 'pink', or black vs. white.

So we have a whole array of colors, and values and temperature to record our data. And that doesn't even touch on texture. Y'all know what texture is - all touchy/feely.
