Colors of the rainbow

• Colors of the rainbow are always arranged in the same order because of the length of the individual light rays.
• Remember, we see a rainbow because of light breaking down through the rain drops (sort of like a prism).
• A way to remember them is Roy G. Biv, a man's name. The order stands for Red, Orange, Yellow, Green, Blue, Indigo and Violet (also known as purple).
• Indigo is a blue-violet color, why it is listed and other colors like yellow-orange can blue-green aren't, I'm not sure.

Newton divided the spectrum into seven named colors: red, orange, yellow, green, blue, indigo, and violet. He chose 7 colors out of a belief, derived from the ancient Greeks, that there was a connection between the colors, the musical notes, the known objects in the solar system (at that time only 7 planets were known), and the days of the week. ��According to modern research, the human eye is insensitive to indigo's frequencies, and some otherwise well-sighted people cannot distinguish indigo from blue and violet. For this reason some people, including Isaac Asimov, have suggested that indigo should not be regarded as a color in its own right but merely as a shade of blue or violet.

Color Wheel

• The Color Wheel is a diagram that organizes colors. It can be reproduced by just remembering the placement of three colors: Red, Yellow and Blue. These colors can be used to make all other colors. Yellow is always placed at the top, Red to the left and Blue to the Right forming an equilateral triangle.
• The purpose of the color wheel is to show the relationship of colors to each other.

- organizes HUES

Cool Colors

Suggest water, grass, and shadows

Warm Colors

Suggest heat fire, and flames

Three Properties of Color�����All colors possess three basic qualities.�Hue, Value. Intensity

HIV

Hue is another word for color and it is basically means the color pigment present

• All of these have the basic hue of red!

Hue

• The first row above shows the natural value of each full strength color
• The second row shows orange and how it has been made to be all the steps of value. White was added to the right of full strength orange and black to the left.

• Hint to remember these:
• Tint - Lighter, Tint and White all have "i" for vowels.
• Shade - Darker, shade and Black all have "a" for vowels.

​

Value

​

​

​

​

​

• Value scales of each of the colors. Notice that it takes more steps
• to make some lighter and darker.

• involves the lightness and darkness of a color. A color is made lighter by adding white and darker by adding black. Each color also has natural value. From lightest to darkest are: Yellow, Orange, Red and Green, Blue and Violet.

Value

• Example viewed in the value unit when we discussed color value

• White comes from the paper – not the paint

​

• Wet the paper where the paint will go – ‘capillary action’

​

• Water & gravity float the colour downhill

​

• The brush controls the flow

​

• The brush mops up excess water – a cloth mops the brush!

​

• Other colours can be fed into the wet paint

Intensity

• is the brightness or dullness of a color. A color can't be made brighter than the way the pigment comes to you in the paint tube.

• In this example, full strength orange on the left slowly has a little bit of blue (it's compliment added to it). This creates tones of orange. As you progress across the scale you reach neutral in the center because there is too much blue mixed with the orange and it has become a neutral. If you start on the right with the blue and slowly add a little orange you can see tones of blue until you reach the neutral in the center.

​

​

​

Left example has high intensity. It's very bright.

​

Right example is low in intensity. It's very dull.

​

And you can change how MUCH of each colour to add.

This produces a huge number of colours!

​

Now to add WHITE………….. (then the colours are called ‘tints’)

This effects the VALUE of the HUE.

CHALLENGE!

Collect colour swatches from magazines. Arrange them in your own order. You will later paint these.

Make sure the colour swatches are +/- 20mm x 20mm

TIPS

• What HUE is it? (Name of the closest pure ‘colour’)
• What VALUE is it? (How light is it? How much white should you add?)
• What INTENSITY is it? (What complementary colour should you add and how much?

Yolisa’s Collage Cloud

​

She will now pick any colour and mix it using the HIV method.

HUE

VALUE

INTENSITY

​

When the colour is dry, she will cut it out and glue it in place with a small label on WHAT colours she mixed, and HOW she mixed them.

​

Some colours will be pure paint – which are those? Write down their names.

CHALLENGE!

Choose the colour you want to make from your collage cloud.

What HUE is it? (Name of the closest pure ‘colour’)

• What VALUE is it? (How light is it? How much water should you use? OR.. How much white should you add – for acrylics and oils?)
• What INTENSITY is it? (How bright or dull is it? What complementary colour should you add and how much?)

CHROMATIC GREYS

What are they? �[Define them and explain how to make them]

​

Make the following: �(Name them with their ‘common’ names!)

1. Light warm grey - 2 different types
2. Cool dark grey - 2 different types
3. Mid cool grey - 2 different types
4. Light cool grey - 2 different types
