Ray has spoke about the benefits of getting morning exposure to red light. This is to explain how the color change occurs and the magnitude of the changes in the colors that occur during the day.

Colors near the red end of the spectrum scatter the least when they travel through the earth's atmosphere. This happens because of longer wavelength of the reddish colors. During sunset and sunrise, sunlight needs to travel more distance to reach us. Red color is able to reach us because it is scattered the least. Hence, sky appears reddish during sunrise/sunset.
First, it is important to remember that the brightness is of sunlight is much greater than the light bulbs that are normally used indoors. Sunlight can be 10X greater than a bulb.
In the image below, there is much less blue light in the evening and at night than there is midday (noon). Inside sunlight has much less light in the red color of the spectrum as compared to natural light. In addition, it has comparatively less blue light. Hence, it best to speed time outside since the light is both brighter and natural. In the morning and evening it has less of the damaging blue light.
The light spectrum become more unnatural when we use artifical lights inside.
I was suprised that incandescent light does not have enough blue light. Some people may be effected by not having enough blue light in the morning. These would be people who do not get outside in the morning and use incandescent light. I posted a study about it.

The sky appears reddish during sunrise/sunset but it appears white at noon. At noon, the sunlight has to travel less distance to reach us. Most of the colors reaching us get scattered. Due to this, the sky appears whiter (or a lighter blue).

Ray Peat has cautioned us about the harmful effects of blue light and wavelengths of radiation that are shorter than the blue wavelengths. However as is often the case, the dose is the poison. The study below suggests that an intentional addition of a small dose of blue light in the morning...
