April White Flowers2
Feature: White Flowers (April Edition Part 2)
Here is the second installment featuring white flowers blooming in April. Before delving into flower descriptions, let's summarize some points about color:
Mixing paint and light results in different colors.
When mixing the three primary colors of paint - red, blue, and yellow - the result is black due to absorption. However, when mixing the three primary colors of light - red, green, and blue - the result is white.
Sunlight is decomposed.
Through experiments using prisms in elementary school, we learned that sunlight is decomposed into about seven colors. We have also experienced seeing a rainbow of seven colors in the sky after rain, which occurs due to sunlight undergoing a similar phenomenon when it encounters raindrops.
When light hits an object, it is broken down into absorbed light, transmitted light, and reflected light, with the reflected light determining the object's color.
From the above, when observing flowers:
"Color of the Flowers"
Flowers come in various colors such as red, pink, yellow, and white. The differences in flower colors depend on the pigments they contain.
When light hits a flower, it separates into absorbed light, transmitted light, and reflected light, with the reflected light determining the flower's color. For example, sunlight hitting a flower with yellow pigment will reflect the yellow pigment, making the flower appear yellow. The same applies to flowers of other colors.
"White Flowers"
However, in the case of white flowers, they contain little to no pigment, so light is scattered, resulting in the appearance of white due to the principles of the three primary colors of light.
However, this is how they appear to the human eye, and the perception may be different for insects and other organisms. It might be interesting to simulate how insects perceive colors using ultraviolet cameras.
Furthermore, besides pigments, the color of flowers can also be influenced by surface hairs or fine structures. We'll introduce this topic separately.
