There are stereotyped object colors that are highly prevalent in fiction, but do not reflect RealLife color variations. They have become embedded in popular consciousness through sheer repetition, to the point that exceptions just seem ''odd''.

[[folder: Purple Grapes ]]
'''

In RealLife, grapes can be purple, yellow-green, red violet, and red, but in fiction, they're purple because purple is the color grapes are associated with. Green might be used, but it would give the impression the grapes are underripe.

[[folder: Blue or Light Blue Water ]]
'''

In RealLife, water comes in a wide range of colors, including clear, turquoise, cyan, light blue, blue-green, dark green, dark blue, and the stereotypical bright shade of blue.[[note]] In real life, water has a very faint blue tint. However, when watching small amounts (such as a glass of it), it will appear completely transparent. Only when watching large enough bodies of water does the blue tint show to the human eye. If water reflects light from a blue object (such as the sky), or is in front of a blue object, it will appear bluer than it "should". [[http://en.wikipedia.org/wiki/Color_of_water The other wiki has a more in-depth explanation]].[[/note]]

Not so much in fiction, where water is usually a bright shade of blue. WaterIsBlue because it's easier to animate than a transparent liquid and because large amounts of water appear blue due to the way it diffuses light. This subtrope, which is highly prevalent in fiction, does not reflect how RealLife water is entirely accurately.

[[folder: Green or Yellow Green Acid ]]
'''

It even has a shade [[http://onlinedictionary.datasegment.com/word/acid+green named after it]] despite the fact that green acidic substances are rare, and no strong or commonly used acids are green.

'''[[/folder]]

[[folder: Green or Yellow Green Grass ]]
'''

In fiction, grass is usually green or yellow green because green or yellow green grass is iconic and easily recognizable.

In RealLife, golden yellow, light brown, and sandy yellow, as well as the stereotypical green and yellow green, are common colors for grass.

[[folder: Green or Yellow Green Radiactive Nuclear Waste ]]
'''

Green and yellow green are the colors associated with nuclear waste, radiation, and anything nuclear even though this is seldom the case in RealLife. Cherenkov radiation in the pools of nuclear reactors is ''[[http://www4.nau.edu/meteorite/Meteorite/Images/Cherenkov.jpg blue]]'', radioactive cesium chloride fluoresces faintly blue, and hot radioactives are [[http://en.wikipedia.org/wiki/File:Plutonium_pellet.jpg orange]].

The association with the colors green and yellow green and nuclear waste comes from peoples' experience with radium painted watch dials, which glow pale green. Watch dials haven't contained radium for decades. Currently they use a similar sort of paint but no radium; it absorbs light when placed in light and then glows for a while in the dark.

[[folder: Yellow Sun ]]
'''

In RealLife, the sun is white or yellowish white, but in fiction its yellowness is played up because yellow is the color associated with the sun.

'''[[/folder]]

[[folder: Yellow or Gold Stars ]]
'''

In RealLife stars can be pretty much any color, but the stars the naked eye can see in the night sky are white. In fiction, stars in the sky--especially those drawn as large, five-pointed "sticker" stars--are usually yellow to [[ColorContrast contrast the night sky's dark blue]].

Star-shaped stickers and badges are virtually always gold in fiction because they're given out in a congratulatory manner--in other words, they're a proxy for a gold medal. Needless to say, in RealLife you can get star stickers and badges in pretty much any color, though gold is still the most popular.

[[folder: Yellow or Orange Cheese ]]
'''

Cheese comes in many colors, including yellow, orange, yellow-orange, light yellow, red, white, and even blue, but in cartoons, it's hard to any examples where cheese hasn't been depicted cheddar yellow-orange or orange.

Bright orange cheeses, especially cheddar, are usually that color because [[http://www.straightdope.com/columns/read/1284/why-is-cheddar-cheese-orange it's been colored]].

'''[[/folder]]

[[folder: Orange Carrots ]]
'''

Almost all carrots in fiction are bright orange because an orange carrot is iconic and easily recognizable and orange is the most common color seen in Reallife Western carrots. [[note]]Yellow and purple are the most common colors in Eastern carrots[[/note]]

This association with the color orange and carrots is NewerThanTheyThink, as the common orange carrots in the Western world were only bred that color a few centuries ago by farmers in the Netherlands, out of patriotic reverence for the House of Orange-Nassau. Before this, most carrots in the West were actually [[PurpleIsTheNewTrope purple]]. No, ''really'', carrots used to be ''[[http://www.google.com/images?hl=en&q=purple%20carrot&um=1&ie=UTF-8&source=og&sa=N&tab=wi&biw=986&bih=680 purple]]''. [[http://commons.wikimedia.org/wiki/File:Carrots_of_many_colors.jpg And carrots come in other colors, like yellow, red, purplish red, and white]].

'''[[/folder]]

[[folder: Red Apples ]]
'''

Most apples in fiction are bright red because a red apple is iconic and easily recognizable.

In RealLife, apples come in a wide range of colors, including red, orange, yellow, and green, and can be more than one of those colors as well.

A common exception would be "sour apple" or candies that are apple flavored - which are often green.

'''[[/folder]]

[[folder: Red Fire Hydrants ]]
'''

In RealLife, they come in a wide range of colors, including yellow (both light and golden shades), pink, white, dark green, orange, dull shades of red, and the stereotypical bright shade of red, and can even have two or more colors on them.

Not so much in fiction, where almost all fire hydrants are bright red. Fictional fire hydrants are usually red because a red hydrant is iconic and easily recognizable. This subtrope, which is highly prevalent in fiction, does not reflect how RealLife fire hydrants are.

[[folder: Brown or Green Polluted Water ]]
'''

Water intended to look polluted is colored either olive green, yellow-green, or brown rather than blue or clear.

Same concept is also commonly applied to swamp water, "blackwater" in real life can look brown, tan, greenish, or pitch black.

'''[[/folder]]

[[folder: Skin Color ]]
'''

The skin colour of white people nearly always depicted as pink, and we're told it's pink, but in reality its a much more subtle selection of light browns, translucency, red beneath the skin, with some blue.
