Color

Color (American English) or colour (Commonwealth English) is the visual perceptual property corresponding in humans to the categories called red, blue, yellow, etc. Color derives from the spectrum of light (distribution of light power versus wavelength) interacting in the eye with the spectral sensitivities of the light receptors. Color categories and physical specifications of color are also associated with objects or materials based on their physical properties such as light absorption, reflection, or emission spectra. By defining a color space colors can be identified numerically by their coordinates.

Because perception of color stems from the varying spectral sensitivity of different types of cone cells in the retina to different parts of the spectrum, colors may be defined and quantified by the degree to which they stimulate these cells. These physical or physiological quantifications of color, however, do not fully explain the psychophysical perception of color appearance.

The science of color is sometimes called chromatics, colorimetry, or simply color science. It includes the perception of color by the human eye and brain, the origin of color in materials, color theory in art, and the physics of electromagnetic radiation in the visible range (that is, what we commonly refer to simply as light).

Greeks (finance)

In mathematical finance, the Greeks are the quantities representing the sensitivity of the price of derivatives such as options to a change in underlying parameters on which the value of an instrument or portfolio of financial instruments is dependent. The name is used because the most common of these sensitivities are denoted by Greek letters (as are some other finance measures). Collectively these have also been called the risk sensitivities,risk measures or hedge parameters.

Use of the Greeks

The Greeks are vital tools in risk management. Each Greek measures the sensitivity of the value of a portfolio to a small change in a given underlying parameter, so that component risks may be treated in isolation, and the portfolio rebalanced accordingly to achieve a desired exposure; see for example delta hedging.

The Greeks in the Black–Scholes model are relatively easy to calculate, a desirable property of financial models, and are very useful for derivatives traders, especially those who seek to hedge their portfolios from adverse changes in market conditions. For this reason, those Greeks which are particularly useful for hedging—such as delta, theta, and vega—are well-defined for measuring changes in Price, Time and Volatility. Although rho is a primary input into the Black–Scholes model, the overall impact on the value of an option corresponding to changes in the risk-free interest rate is generally insignificant and therefore higher-order derivatives involving the risk-free interest rate are not common.

Color (manga)

Color is a Japanese manga anthology written and illustrated by Taishi Zaou and Eiki Eiki. Color was serialized in Dear+, a magazine known for its romantic and non-explicit boys love manga published by Shinshokan, and a tankōbon collecting the chapters released in February 1999.Color is licensed in North America by Digital Manga Publishing which released the manga in June 2009. It is licensed in France by Asuka and in Germany by Egmont Manga.

[Verse1]
She said "let it slide"
All the things that I
Have running through my mind
Will all be gone in time
Remember son
All the things you've done
And all the things you lost
And all the things you won
[Pre-chorus]
We're just trying to find some color in this
black and white world
[Chorus]
Tell me everything will be alright
Walk this way with me into the night
'Cause you can let it slide
Baby just for the night
Just know that everyone feels broken sometimes
[Verse2]
She said "take your time"
Things will be just fine
Don't bite the hand that feeds
'Cause nothing's ever mine
And just wait your turn
And always try to learn
To love the ones that don't show love in return
[Pre-chorus]
We're just trying to find some color in this
black and white world
[Chorus]
Tell me everything will be alright
Walk this way with me into the night
'Cause you can let it slide
Baby just for the night
Just know that everyone feels broken sometimes
[Bridge]
When you're walking backwards
Don't be afraid to close your eyes
'Cause the truth is, darling
That everything will be alright(alright)
[Chorus]
Tell me everything(tell me anything)
Walk this way with me(just tell me everything)
'Cause you can let it slide
Baby just for the night
Just know that everyone feels broken sometimes
[Chorus]
Tell me everything will be alright
Walk this way with me into the night
You can let it slide
Baby just for the night
Just know that everyone feels broken sometimes
Oh yeah, everyone feels cheated sometimes
