Color Concepts

Print Friendly and PDF


By Jim Hingst @hingst_jim

When you are learning about color, three concepts that you will need to grasp and add to your vocabulary are: hue, value and saturation. 

Hue is synonymous with the color itself, such as blue, green, yellow, orange, red.  On a color wheel, the yellow, blue and red are described as the primary colors. 


Value describes the lightness or darkness of a color. And saturation refers to the brightness or dullness of the color. 

To the physicist, color is nothing more than wavelengths of light.  If you combine all of the frequencies of light together, the result is white light.  If you pass that white light through a prism, the light is divided into the spectrum of colors.

The receptors in our eyes detect three of the frequencies of light: red, green and blue. Our brain responds to the messages from these receptors to create our perception of color.

The Color Wheel

Think of the traditional color wheel as the spectrum of colors arranged in circle. The value of a color wheel is as tool to aid you in mixing of colors. The three primary colors on wheel are red, yellow and blue. 

Secondary Color. By mixing two adjacent colors on the wheel, you create a secondary color. Mixing red and yellow produces orange. Yellow and blue creates green. And, red and blue yields purple.

Tertiary Color. By combining a primary and an adjacent secondary color on the color wheel, you produce a tertiary color. For example, mixing red and orange produces red orange. In naming the tertiary colors, the primary color is always given first, and then the secondary color. 

Triad. The term triad refers to three colors, which are equally spaced on the color wheel, such as the three primary colors: red, blue and yellow.

The Natural Value of a Color

When you are trying to decide which color to use with a particular background color, one consideration is the natural value of the color.  Any color has an inherent lightness or darkness of it.  White has a value of 10. Yellow, for example, can have a value of 8. Red can have a value of 5 or 6.  The value of purple is 7 or 8.  Black has a value of 0. 

Every “hue” or color can have a range of values. You can change the value of any color by adding either white or black to it. Just remember that when you mix black or white with another color, you diminish the color’s “intensity”, which describes the purity of a color.

Saturation or chroma refers to the brightness or dullness of a color.  High saturation of a particular color is called bright. Imagine the brightness of a color in the middle of the day.  As the day gets closer to night, that color loses its intensity and gradually appears more grey. Finally, at nighttime, we see no colors; if we see anything at all, it appears black and white or grey. At this point, the color loses the characteristic which defines it as a color and it becomes achromatic.

Vinyl Application Videos

Squeegee Technique. Nothing is more basic in vinyl application than the squeegee. But some squeegees work better than others. And there are right ways and wrong ways to use this simple tool. This video clip reviews squeegee selection, squeegee care and squeegee technique. Click to Link

Wet Applications. Dry applications are typically recommended for most vinyl applications. For those exceptions to the rule, this instructional video explains the right way to perform a wet application. Click to Link

Application of Window Graphics. Installing vinyl graphics on glass can be challenging, because the adhesive aggressively grabs onto this high energy surface. Repositioning graphics on window is generally difficult, if not impossible. This instructional video explains how to dry apply window graphics right the first time. It also describes the necessary steps required for surface preparation. Click to Link

Transferring Frosted Window Graphics Films.  Because frosted window films are highly textured, transferring cut vinyl graphics can be problematic. This video provides direction in selection of the right application tape and how to apply these films quickly, easily and without problems. Click to Link

3-Step Surface Prep. This instructional video describes how to properly clean the surface of a vehicle before applying pressure sensitive vinyl graphics to a trailer or doing a full wrap of a car or van. This three step surface prep involves detergent washing, solvent cleaning and a final wipe down with IPA. Click to Link


Vinyl Application Over Rivets. Applying vinyl graphics on vehicle surfaces with rivets is challenging for most sign makers. Vinyl failures to these surfaces are all too common. This video demonstrates some tips and procedures, used by professional decal installers, which will make these demanding applications easier and more trouble-free.  Click to Link

Vinyl Application to Corrugations. Learn how to apply vinyl graphics to corrugations in a relaxed state. Forcing films into the valleys of corrugations puts too much mechanical stress on the film. Sooner or later, the vinyl will lift or tent in valleys. Click to Link

Applying Air Egress Vinyls. Vinyl films with air egress release liners have almost eliminated bubbles and wrinkles from applied graphics. Air egress release liners with their highly textured surface structure are problematic. Not much will stick to these liners other than the vinyl film. At RTape our best premask solution for air egress liners is a special Conform® tape called 4761RLA. Click to Link
