Does the spring orchid bud change color when it blossoms when it sees the sun?

The color of orchids is determined by genes and does not change color due to the intensity of sunlight. So you worry that it is superfluous to change color after seeing the sun. But although the color remains the same, the depth of the color is directly related to the intensity of the light. For example, if the varieties of red flowers are exposed to sufficient light at the bud stage, the color of the flowers will be darker red after blooming. On the contrary, if the light is less, the color of the flower will become lighter. If it is artificially covered with black cloth or tile tube, so that it is in the dark without light from the bud to flowering, the color of the flower will be lighter and a rare pink color will appear. Nowadays, some unscrupulous orchid vendors use covers to cover buds or pedicels to make them bloom fake peach flowers in no light or low light, so as to deceive consumers.
