Spanish lesson for kids: Learning about colors

Colors, magnificent as they are, can describe the very essence of where we live. They illustrate every single detail about where and how we see the world around us. From a shirt to a milk cup, colors can tell us whether the shirt is red or the milk cup is yellow. But how can our eyes detect and identify the different colors we see?

In this lesson, you will learn about how colors appear, names in English and Spanish, primary colors, and secondary colors.

Lesson objectives:

  • Learn Spanish colors using vocabulary and visual aids
  • Use learning worksheet to identify colors
  • Use learning worksheet to verbally identify colors and print awareness

Colors are manifestations of light and how it travels on earth. Light can travel as a wave. But not all light waves are the same. Many of them can either be short or long, depending on how they are categorized in the light spectrum. The arrays of light, in the scale of short and long waves, can tells us whether a long light wave is in the infrared range or a short light wave is in the ultraviolet range.

In this light spectrum, the red, orange, and yellow identify the microwave range, green identifies the infrared, blue identifies the visible region, and indigo and violet identify the ultraviolet range. In this way, light manifested in the infrared range of the spectrum is seen as the red color. All the other colors follow in the same way. But what about the rest of the other beautiful colors we see?

These intermediate colors are merely combinations of primary and secondary colors. Primary colors are classified as red, yellow, and blue. Secondary colors are classified as orange, green, and purple. When these primary and secondary colors are mixed in infinite possibilities, intermediate colors of pink, light blue, brown and other colors begin to form.

Even precious metals like gold, silver, or copper can enhance the appearance of objects. However, they are not colors, but representations of light behavior on certain metal surfaces. In the same manner, black absorbs all the light rays. And white reflects all of the light rays. Hence, black and white colors are not regarded as part of the light spectrum. Yet, there are the extremes of the array of colors.

If primary and secondary colors are part of the light spectrum, then these are displayed in a rainbow, too. These beautiful arcs of color are extraordinary arrays of light in the presence of moisture in the atmosphere. As sunlight interacts with water droplets in the sky, light waves begin to reflect and refract. Water acts as a prism, an optical device to direct the behavior of light waves, in the air. Hence, as long light waves pass through water droplets, the red color is exhibited in a rainbow.

As many other intermediate light waves pass through, the different colors: orange, yellow, green, blue, and indigo, are displayed on a rainbow. Then, short light waves demonstrate the violet color. Sometimes rainbows may only display the primary colors. In very rare cases, two rainbows can be observed. However, all rainbows can show all seven colors of the light spectrum.
