| Oct 11, 2021 at 11:37 | comment | added | Ruslan | @SureshChandraPal that's basically right. In the evening sunlight has much smaller amount of blue, and somewhat smaller amount of green, so you get a noticeable tint of orange in the reflected light. I.e. if at noon you get "small blue, large green, small red", then in the evening the reflected light is "almost no blue, some green, some red", and this looks like orange. | |

| Oct 11, 2021 at 11:19 | comment | added | user313211 | So that I am saying sir, that in noon or white light time from sun, there is reflectance of other color too from leaf other than green but in a much small amount compared to green, in noon other than green , other color of spectrum reflect but all of them 'almost' small amount and equal amount but green in high amount , thus dominating and other colors of spectrum doesnt notice. But during evening green is reflected but along with it orange (left most in spectrum due to scattering) reflected and orange color (along with much green) I absence of other bluish color of spectrum creat.... | |
| Oct 11, 2021 at 10:59 | comment | added | Ruslan | @SureshChandraPal you should make a clear distinction between color and frequency. The color of an object is composed of a lot of frequencies in different proportions. A green object will have more reflectance in the green range of the spectrum, but may have nonzero reflectance in other parts of the spectrum. In particular, if you look through a red filter at a leave lying on a wet soil, you'll see that the leave is brighter than the soil. This must mean that some red is reflected from the leave, so not all of it is absorbed. | |
| Oct 11, 2021 at 10:41 | comment | added | user313211 | So that mean we are adapted to white colour, in noon along with green ,some sun rays are reflected by leaf, but we don't notice it and green colour of leaf dominate over white patches of direct rays. Although in evening there is some unusual 'colored rays like golden or orange that attracts and seem new to eye and hence it is noticed along with green color if leaf. Overall....U mean along with respective color of colored object, some amount of other colors(not that of object) is also reflected? | |
| Oct 11, 2021 at 9:29 | comment | added | Ruslan | When the sky, as in the morning or evening, is the main contributor to illuminance, our eyes&brain adapt to the blue illuminant, so the orange/golden patches of direct sunlight look high-contrast orange. With direct sunlight or moonlight, Sun & Moon dominate, so we adapt to their (white) colors. The leaf colors are evaluated with respect to the dominating illuminant, and when there are no "unusual" light patches on the leaves, the color looks green. | |

| Oct 11, 2021 at 9:06 | comment | added | Ruslan | @SureshChandraPal that's because of chromatic adaptation. | |
| Oct 11, 2021 at 8:54 | comment | added | user313211 | But ,in noon also this means some of the sunlight is reflected back ....but we don't notice it , simply we see a green color leaf. But as in morning or sunset when light is reddish yellow , we start seeing a golden patch. So why don't in noon we see white patches ? And only green color of leaf? | |
