'''Colour ''' is something we [[Sight|see]] with our [[Eye|eyes]].

: Singular [[Noun]]: '''Colour''': Plural [[Noun]]: ''': Colour: Colours''': [[Verb]]: ''': Colour'''

The '''colours''' we can see are red, orange, yellow, green, blue, indigo and violet. If you mix '''colours''' of [[paint]] together you can get another '''colour'''. Red and yellow paint mixed together makes orange. Blue and yellow paint mixed together make green. Blue and red paint mixed together makes purple. If you mix all three you can make brown.

|The Grass is a green '''texturecolour''' of a snake's skin is smooth.|Bricks have a rough The '''texturecolour'''of this rose is red.

|A wet fish has a slimy The sky is blue in '''texturecolour'''.|Rocks are usually hard in I will '''texturecolour'''in [[The Sun]] yellow with paint.

==Key Stage 3=====Meaning===[[Colour]] is a [[property]] of [[object]]s that we can [[Sight|see]]. ===About Colour===White [[light]] can be divided into 7 [[colour]]s:*Red*Orange*Yellow*Green*Blue*Indigo*Violet : Red [[light]] has the lowest [[frequency]] and the longest [[wavelength]].: Violet [[light]] has the highest [[frequency]] and the shortest [[wavelength]]. ===Colour and Objects==={| class="wikitable"|-|[[File:RedObjectColour.png|center|300px]]|[[File:BlueObjectColour.png|center|300px]]|-| style="height:20px; width:200px; text-align:center;" |A red [[object]] [[reflection|reflects]] red [[light]] but [[Absorb (physics)|absorbs]] all the others '''colours'''.| style="height:20px; width:200px; text-align:center;" |A blue [[object]] [[reflection|reflects]] blue [[light]] but [[Absorb (physics)|absorbs]] all the others '''colours'''.|} ===Eyes and Colour===: The [[human]] [[eyes]] only have three different '''colour''' sensing [[Cell (Biology)|cells]] called [[Cone (Biology)|cones]]. They can detect; red, green or blue light. All other '''colours''' we see are caused by a pair of different [[Cone (Biology)|cones]] detecting [[light]] at the same time.: If the red [[Cone (Biology)|cones]] and blue [[Cone (Biology)|cones]] both detect [[light]] then we see [[magenta]].: If the red [[Cone (Biology)|cones]] and green [[Cone (Biology)|cones]] both detect [[light]] then we see [[yellow]].: If the blue [[Cone (Biology)|cones]] and green [[Cone (Biology)|cones]] both detect [[light]] then we see [[cyan]]. ===Coloured Mixing==={| class="wikitable"|-|[[File:ColourMixing.png|center|500px]]|-| style="height:20px;

For example [[leaf|leaves]] are green because the [[chlorophyll]] inside them [[Absorb (Physics)|absorbs]] red and blue [[light]] but not [[green]].: When [[colour]]ed [[object]]s are [[mixture|mixed]] such as paint they [[Absorb (Physics)|absorb]] certain [[colour]]s. The more different [[colour]] paints added, the more [[colour]]s they [[Absorb (Physics)|absorb]].: In art the focus is on these subtractive primary colours; Magenta, Cyan and Yellow. When [[object]]s with these [[colour]]s are [[mixture|mixed]] the [[object]] will preferentially [[Absorb (Physics)|absorb]] certain [[frequency|frequencies]] of [[light]] allowing only certain [[colour]]s to paint be [[reflect]]ed. ====Coloured Objects Under Light Coloured Light===={| class="wikitable"|-| style="height:20px;
