The wikipedia page on photosynthesis goes into a lot more detail. One of the most common pigments is called chlorophyll, and one of the varieties is responsible for the green color of plants; it strongly absorbs blue and red light, which leaves only the green light to make it to our eyes.

Chlorophyll is the most effective pigment, which is why most plants have it. How does light color affect plant growth?

The colors are always in the same order. All of these colors are in white light. The reason for this is the colors in light have different wavelengths and those wavelengths, depending on whether they are short Color effect on plants long, provide different levels of energy.

The red end is lower energy, it has long wavelengths. She won a prize for her project. Blue Color effect on plants will allow the plant to grow leaves and other vegetation and red light with blue allows the plant to grow flowers. For a hungry world just waking up to the effects of Global Warming, this is critical.

Plants have more than one pigment, so they can capture different regions of light, but not all pigments are made equal. Thanks for asking, Answer 2: Here is a short page about the different absorption spectra of light for different pigments in plants.

They still get energy from the red end, but not as much. If you use a prism, you can separate the white light into the colors.

The color or wavelength of light does affect photosynthesis, which is how plants can basically create their own food. The color you see when you look at an object is the color that light is reflecting back at your eye.

The shorter the wavelength the more energy a color has. For example, plants look green because they have a lot of chloroplast in them, which absorbs all visible wavelengths of light except green, so leaves look green to us. Knowing that different colors of light can affect what a plant does is important in a world that depends on plants for food.

Blue light, for example, helps encourage vegetative leaf growth. Yes, color does affect plant growth. Thats what the raindrops are doing when we see a rainbow. Plants are certain colors because their pigments absorb light most effectively in certain regions of the visual light spectrum.

As you know, plants are usually green, which means that most other colors are absorbed. As you know, plants get their energy from light, but you might not know that different colors of light have different energy levels. At the other end of the spectrum, you will find red light which has long wavelengths and emits lower energy.

Cool fluorescent light is great for cultivating plant growth indoors. Now heres the next wrinkle in the story. Purple and violet lights have short wavelengths and thus lots of energy. The plant does not absorb the green light so does not use it to grow.

Plant Growth & Light Color

Different colors of light came through the cellophane sheets of different colors, onto the plants. The ones that give the plant the most energy are the ones at the purple end of the spectrum.

We can now design lighting to encourage flowering or to produce higher fruit yields for example. What may be news to you, however, is that the color of the light has a measurable impact on the amount of energy a plant absorbs.

Different colors are associated with encouraging different parts of plants to grow. Click Here to return to the search form. Regardless of whether the color of the light is red or purple the plant will absorb some amount of energy from the light it is receiving.Color is all around us, but what impact does it really have on our moods, emotions, and behaviors?

Color psychology seeks to answer this question. Red Light vs. Blue Light: Which Light Color Is Better For Plant Growth. The effect of blue light on plants is directly related to chlorophyll production.

Plants that receive plenty of blue light will have strong, healthy stems and leaves. How does light color affect plant growth? Question Date: Answer 1: As you know, plants get their energy from light, but you might not know that different colors of light have different energy levels.

Can Colored Lights Affect How Plants Grow?

Think about the colors of a rainbow. All of these colors are in white light.

Is Plant Growth Affected by Light Color?

If you use a prism, you can separate the white light into. I read some place that plants need more red artificial light because it is the color of heat.
