Color

He must live his life, advance,
build, move, move forward.
Always try to offer.
but do not fight against each other,
or compel or force them.

We must open up to others,
give them warmth,
they bring joy and provide friendship.
We need to celebrate.
We must make the sun shine every one of us
has in his heart. should shine.
But we must respect the space of the other,
must keep his distance, not to invade,
and not to claim his attention.

At this price you can handle things,
you can structure, balance.
Without intransigence, without imposing anything.
Then you meet the love.

It must be moved, cry and feel.
It should open up his emotions.
You must be gentle with others.
But do not weep for the child who remains in us.
And do not be paralyzed.

It takes time for contemplation,
a time to retreat to the solitude.
It takes time to learn, to take stock,
to understand.
A time to depth.
But what you have learned
you will have to teach and not to impose it.
Do not enter into intolerance.

At this price you can open up to the depth.
Where you meet the Divine.
You will meet the creative, beautiful and subtle.
But without going into chaos,
then you will see the signs.

Perceived color yellow, the sun warms us and makes us the joy and celebration

Yellow is the color while sunflower,
which always seeks the light.

It is the color of the first flowers
spring, primroses, daffodils,
which we call the return of happy days.

Yellow is the color of sharing, celebration
and joy.

Gold, which shows
our inner wealth, eternal

and the heart of the egg
which tells us
inside
each heart
is a hidden
sun for others.

Yellow is the color of friendship and radiation.
He needs the contact with others, need to enlighten, and to feel seen.
The yellow loves groups, which he trains and watch him, he likes to exchange and dialogue, and share with others.
It is radiant, but also demanding in sharing and friendship.
And if not watched, it is pride and vanity.

Blue is the color of the ocean,
and color space.

The dark blue comes back
depth,
the lack of sensation.

And in this infinite space, in the absence of reference, it is the thoughts, reflection, encounter with oneself.
The horizon, ever more distant, pushing us to the discovery, and knowledge.

While the depth of the ocean, or the depth of the cosmos, bring us to the depths of things, and remind us that research is primarily internal.

Dark blue is the color for that understanding.
It reflects our need to understand, to answer our questions, our research ourselves, who we are and where we go.

Blue has a constant need to discover and understand, teach. He wants to share, explain and bring ideas.
But if he can not be heard, reject, isolate, and return to its depth.

Red is the Color of Blood eur
and the body color.
It is also the color of the earth.
The land which is the body of life.

red is rooted in the body in the drive, in action, and perception.

It is the color of the life instinct,
but also the strength
and affirmation of his will.
But red also mark the acceptance of life, respect for life
and love for life.
Red is the color when the speed
and sports cars,
and color of the actions of life: red cross

The color red is the color of the struggle, revolutionary, or in the arena.
And it is also the color of sex and violence, the color of fire burning passion.

Being red is being energetic, always up to new projects, always combative, determined and eager to succeed.

But red is proud, steeped in ambition and craving for power, a color that wants to be seen, and impose on others.
It also has its bad side, because of violence and tyranny, and crimes of rage.

Color Printing

The brain synthesizes a colorful printing from three color information given by the eye: the quantities of blue, red and green. This information is provided by three types of cells (cones) of the retina.
By varying the amounts of blue, red and green light entering the eye, can give the brain the impressions of all visible colors.

In the simulation below, three slide projectors, fitted with blue filters respectively, green and red light up a screen. You can vary the intensity of the beams by moving the mouse to the three sliders. In the square, you’ll see what we see in that part of the screen where the three beams of light are added together. This is called additive color. A prism breaks this light.
Your brain synthesizes a complex color, but physically, the resulting light is composed of only three selected wavelengths through the filters of the projectors.

This is how TV screens and computers visus, each pixel is composed of three points, one blue, one green and one red. To give an impression of color, simply adjust the brightness of the three points.

Color blindness

Color blindness is a disturbance of color vision. A color blind (this condition mostly affects males and is transmitted genetically) sees the same way in different colors.
A current model of blindness described by the lower sensitivity of the three families of cones in the retina. Thus, a colorblind whose cones sensitive to blue light would be seen less effective in the same way color containing the same amount of red and green but the amount of blue is slightly different.
You can test your eyes using the above simulation, set the value of two colors and vary slowly in the third. Do you see any differences?

What to see an object?

See an object is to receive in the eye of light from different points of the object.
View point of an object can be described:
in terms of light wave: the eye receives a spherical light wave whose center is the point.
in terms of light rays: the rays diverge from this point coming into the eye. For a point of an object is seen by an eye, you need:
the object is illuminated by a light source. (we see nothing in the dark!)
that point refers (diffuse) light in all directions. (we do not see the mirrors and transparent objects)
diffused rays that penetrate through the point in the eye. (we do not see what is hidden!)
they diverge from this point.

Real or virtual

It is not important for the eye as the rays diverge from that point, the eye (and brain) will see this item on the spot where the rays seem to come. If the rays actually come from the object (straight line) to the eye, the object is real. If they come to the eye after a circuitous route, the object is virtual.
For example, objects viewed in a mirror we think the plan behind it although the same side as us.

The color of objects The white light is due to the addition of all colors.
The color of a point of an object illuminated with white light is due to selective scattering of light that is received.
A white dot rebroadcasts all colors.
A black dot absorbs all colors and does not broadcast anything.
A red dot pure (monochromatic) absorbs all colors and produces only red.
The color of an item is the result of a subtraction (selective absorption) of light colors to white people talk about “synthesis” subtractive color.

The color of an object depends on:
the manner in which the pigments constituting the point scatter and absorb different wavelengths;
the composition of light that illuminates it, and if an object is illuminated with red pure blue light, it appears as pure red black absorbs all colors, including blue and red only broadcasts it receives not.
and of course the eye and brain of the beholder

In reality, the color pigments diffuse color ranges, the colors are never released pure (monochromatic) is the eye and the brain interprets these ranges in color prints.

On the document attached cons, we analyzed the light scattered by a sheet of white drawing paper, then covered with red felt pen, blue and green. The curves give the brightness of the scattered light as a function of wavelength, therefore the color. The paper was illuminated by light from a slide projector, decomposed by a network and analyzed by a linear array CCD.
We realize that the colors are distributed far from monochromatic! However, the eye and brain are white, green, blue and red
