I'll list them out here so you can easily write them on your paper. I went through the color palette from R to V and listed out all of the combinations.
I used the following code for mine, but feel free to write out your colors fully. Label each box with abbreviations of the color combinations so that you know which two colors will go in each. Measure down 1/4", then 1", then 1/4", then 1", and so on from top to bottom. Now we'll make the horizontal margins for our 1" boxes. Measure in 1/4", then 1", then 1/4", then 1", and so on from left to right. We'll make the vertical margins for our 1" boxes. We'll be making 28 boxes that measure 1" x 1" on our 5.25" x 9" piece of paper. The two-layer technique is a great way to create neutral colors, darker colors, and also more complex colors that don't come in the color pencil box.
We're going to be making a color chart that shows all of the color combinations for our two-layer technique. Still life photo (available as an attachment to this tutorial).Color pencils: Poppy Red, Orange, Canary Yellow, True Green, Grass Green, True Blue, Ultramarine, and Violet.7" x 9" piece of paper (I prefer Stonehenge).5.25" x 9" piece of paper (I prefer Stonehenge).We'll start by making a swatch guide that showcases every color combination we can make, and then use that color knowledge to pencil a still life.
By layering two disparate colors, you can create a non-color-crayon-box color that matches what you see in real life. Colored pencils may seem like a childish medium, but in this tutorial I'm going to show you the two-layer technique.
