‘Apparent colour’ is what one actually sees; it is the colour resulting from the combined effect of true colour and any particulate matter, or turbidity. In turbid waters, the true colour is substantially less than the apparent colour.

The units of luminance are candela per square meter (cd/m2), often referred to as a “nit”. LED Color: The color of a source, again in a particular direction, is described in terms of a color space, the most common of which is the CIE 1931 color space.

Reflected color can be measured using a spectrophotometer (also called spectroreflectometer or reflectometer), which takes measurements in the visible region (and a little beyond) of a given color sample.

Here the colour difference is measured by taking the square root of the sum of the squares of differences in three dimensions following Euclidean geometry. 3. Line element (or distance element) in Riemannian space, which can be used when the colour perception space is non-Euclidean.

‘True colour’ is the colour after particulate matter has been removed (usually by filtration through a 0.45 micrometer pore size filter). ‘Apparent colour’ is what one actually sees; it is the colour resulting from the combined effect of true colour and any particulate matter, or turbidity.

Color – True color is caused by dissolved compounds in water. For example, brown colored water could be the result of dissolved byproducts of plant biodegradation (true color) or suspended clay particles (apparent color) or both (also apparent color).

Clear, or transparent, isn’t considered a color. Thus, it has no color. Objects that are semitransparent, or translucent, have a color of their own, as a significant portion of the light doesn’t pass through and is reflected instead.

The most common cause for water to change color is minerals. Sediment and soil runoff can also change water’s color – sometimes as a temporary color change after storms and sometimes permanently if the river constantly carries lots of sediment. Erosion from river banks brings soil into the river, changing the color.

Earth tone is a color scheme with multiple meanings. In its narrowest sense, it refers to “any color containing some brown” – the color of ground or soil (earth). It can also refer to “natural colors” (colors found in nature) such as brown soil, green leaf, cloudy sky, as well as the red sun.

Explanation: Here are the true colors of planet Earth. Blue oceans dominate our world, while areas of green forest, brown mountains, tan desert, and white ice are also prominent. Oceans appear blue not only because water itself is blue but also because seawater frequently scatters light from a blue sky.

Colour therapy is also the foundation for Vedic gem therapy and basic colours of the planets are: SUN—Red (transparent), MOON—White (opaque), MARS—Red (opaque), MERCURY—Green, JUPITER- Yellow, VENUS—White (transparent), SATURN—Blue.

Pluto’s visual apparent magnitude averages 15.1, brightening to 13.65 at perihelion. In other words, the planet has a range of colors, including pale sections of off-white and light blue, to streaks of yellow and subtle orange, to large patches of deep red.

Order Of the Planets From The Sun

• Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. An easy mnemonic for remembering the order is “My Very Educated Mother Just Served Us Noodles.”
• Mercury:
• Venus:
• Earth:
• Mars:
• Jupiter:
• Saturn:
• Uranus:

Of the objects that orbit the Sun directly, the largest are the eight planets, with the remainder being smaller objects, the dwarf planets and small Solar System bodies….Solar System.

The average temperature on Venus is 864 degrees Fahrenheit (462 degrees Celsius). Temperature changes slightly traveling through the atmosphere, growing cooler farther away from the surface. Lead would melt on the surface of the planet, where the temperature is around 872 F (467 C).

Venus is sometimes called Earth’s twin because Venus and Earth are almost the same size, have about the same mass (they weigh about the same), and have a very similar composition (are made of the same material). They are also neighboring planets.

The hottest planet in the solar system is Venus with an average temperature of 464 degree Celsius and the coldest planet in the solar system is Pluto with an average temperature of -225 degree Celsius.
