Why do early spring flowers tend to be more yellow, than any other colour, after the snowdrops?

Spring flowers are beautiful aren't they?  The reason the majority of them are yellow is reproduction.  What color are you most likely to see from a distance?  Yellow is very bright and attracts bees and hummingbirds, for example, which then pollinate them.  Nature is pretty incredible if you really think about it.  Hope that answers your question.  Have a nice day!

Blue is the color that reflects off snow in early evening and before dawn. Its a comfort thing. People want that color reflecting off their homes to let their visitors know they are welcome.

The spring season starts on March 20th or 21st depending on when the equinox is. The equinox is when the length of day and night is equal and happens twice a year in spring and autumm. Spring ends in May. This is only offically the weather changes and means that our winters are getting shorter and flowers are growing much earlier then ever before.

Reduction in light and in some cases lower temps for some trees kill the chlorophyll.  This lets the other pigments(reds and yellows) show through that have always been there but were hidden by the abundant chlorophyll.

Most of the time it's during the spring, but the reason is solely based on water temperature.  If you have an exceptionally cold early spring, they won't start spawning until late spring.  Once the water temperature gets in the high 50's to low 60's they'll start moving up and shortly thereafter, the spawning period will begin.

Deciduous trees leaves turn yellow because they die in autumn.Evergreen well don't die off,hence stay green.

As summer ends and autumn comes, the days get shorter and shorter. This is how the trees "know" to begin getting ready for winter.\n\nDuring winter, there is not enough light or water for photosynthesis. The trees will rest, and live off the food they stored during the summer. They begin to shut down their food-making factories. The green chlorophyll disappears from the leaves. As the bright green fades away, we begin to see yellow and orange colors. Small amounts of these colors have been in the leaves all along. We just can't see them in the summer, because they are covered up by the green chlorophyll.\n\nThe bright reds and purples we see in leaves are made mostly in the fall. In some trees, like maples, glucose is trapped in the leaves after photosynthesis stops. Sunlight and the cool nights of autumn cause the leaves turn this glucose into a red color. The brown color of trees like oaks is made from wastes left in the leaves.\n\nIt is the combination of all these things that make the beautiful colors we enjoy in the fall.

The sun shines.. the birds sing, the plants blossom and bloom.. unless you're in f*cking England, then the sky stays grey and everyone is miserable right through until June, when we get around two and a half weeks of sun and thats it.

Leaves turn colors in the fall because the tree stops supplying the leaf with water.  This stops the process of photosynthisis which is where the chlorophyll in the leaf changes sunlight into energy.  The green chlorophyll start turning yellow, red and brown for lack of food.  The leaves fall off the tree and die, allowing the tree to store water for winter and live on until spring.

Most perennials are spring or summer blooming plants. There are hundreds to name, foxglove, cosmos, snapdragons, etc.\n\nSome bulbs also are summer bloomers, but a lot bloom in the early spring even through snow (like crocuses and daffodils)

maybe yellow jaundice hence yellow

During spring....\n\nThe sea isn't too cool, and the sun isn't too high.

The same thing that causes prizms in crystals.  It is the colors of light, the rain condenses them just as the crystal does

The "white" is caused because snow has a great many tiny interfaces, called "phase boundaries," where air (a gas phase) meets ice (a solid phase). Every time light encounters a phase transition, it is defracted. If you've ever looked at a stick submerged partially, you've seen this--a straight stick will look like it has a bend in it right at the water's surface. Well, with snow, the tiny ice crystals, and the many small bubbles in ice (water is a bent and polar molecule, so when it freezes, it expands, making small bubbles inside), and the places where individual ice crystals begin and end--all of this scatters light all around. This makes it so that a big bunch of snow will look white. If you look at a single snowflake under a microscope, though, you will see that the crystals individally are clear.\n\nWhen it melts, there is only one phase transition, right at the surface. The light is defracted a bit, but only once--it doesn't scatter light all around like snow does.\n\nBut it can! If you've ever seen a big fountain, where the water is splashing and tumbling about, it will also look white due to phase transition. Likewise, if you make a whole bunch of tiny bubbles under water, you can scatter light and make it look white.

Why is the Sun yellow? \nIt isn't, really. The color yellow is a purely human interpretation of a collection of radiation that hits the retinae of our eyes and gets processed by our visual cortex. \nAnimals seem to have some analogous way of discriminating light by some kind of 'coloration' sense, but we have no way to know if their brains actually 'see' the same thing we do when they look at 'yellow' light. Color detection is caused by photosensitive cells called 'cones', and some animals have none of these and would see the Sun as, presumably some shade of grey since there retinae have the black-white sensitive 'rods' instead, and which have a greater light sensitivity.

the frost comes out of the earth slowly around here, but when it does the rich loamy smell of the ground hugs the air.  this is the first "smell" of spring i notice... that earthy pungency, especially on those nights where you can almost taste the mist in the air.\n\nthe sun gets higher and heats last year's leaves and grass... the smell of old things heated and dried has an almost sweet aroma to it.  it adds its voice to the earthy darkness.\n\nand finally as the spring blossoms in earnest (it just started last week!)  the sweet smell on the wind of growth.  grass greens... buds swell... a few brave bulbs blossom... the balsam fragrance of the trees in the woods... how bright the colors are, and the fragrances.  were they really this extravagant LAST year?  no way...

snow isn't really white its just the amount of light that is bounced back so when it melt it changes states of matter and becomes a liquid which bounces back light differently
