<h1>[name]</h1>
<p class="desc">
Class representing a color.
</p>
<h2>Examples</h2>
A Color can be initialised in any of the following ways:
<code>
//empty constructor - will default white
var color = new THREE.Color();
//Hexadecimal color (recommended)
var color = new THREE.Color( 0xff0000 );
//RGB string
var color = new THREE.Color("rgb(255, 0, 0)");
var color = new THREE.Color("rgb(100%, 0%, 0%)");
//X11 color name - all 140 color names are supported.
//Note the lack of CamelCase in the name
var color = new THREE.Color( 'skyblue' );
//HSL string
var color = new THREE.Color("hsl(0, 100%, 50%)");
//Separate RGB values between 0 and 1
var color = new THREE.Color( 1, 0, 0 );
</code>
<h2>Constructor</h2>
<h3>[name]( [param:Color_Hex_or_String r], [param:Float g], [param:Float b] )</h3>
<p>
[page:Color_Hex_or_String r] - (optional) If arguments [page:Float g] and [page:Float b] are defined, the red component of the color.
If they are not defined, it can be a [link:https://en.wikipedia.org/wiki/Web_colors#Hex_triplet hexadecimal triplet] (recommended), a CSS-style string, or another Color instance.<br />
[page:Float g] - (optional) If it is defined, the green component of the color.<br />
[page:Float b] - (optional) If it is defined, the blue component of the color.<br /><br />
Note that standard method of specifying color in three.js is with a [link:https://en.wikipedia.org/wiki/Web_colors#Hex_triplet hexadecimal triplet], and that method is used
throughout the rest of the documentation.<br /><br />
When all arguments are defined then [page:Color_Hex_or_String r] is the red component, [page:Float g] is the green component and [page:Float b] is the blue component of the color.<br />
When only [page:Color_Hex_or_String r] is defined:<br />
<ul>
<li>It can be a [link:https://en.wikipedia.org/wiki/Web_colors#Hex_triplet hexadecimal triplet] representing the color (recommended).</li>
<li>It can be an another Color instance.</li>
<li>It can be a CSS-style string. For example:
<ul>
<li>'rgb(250, 0,0)'</li>
<li>'rgb(100%,0%,0%)'</li>
<li>'hsl(0, 100%, 50%)'</li>
<li>'#ff0000'</li>
<li>'#f00'</li>
<li>'red'</li>
</ul>
</li>
</ul>
</p>

this color and 1.0 is the first argument.
</p>
<h3>[method:Color lerpHSL]( [param:Color color], [param:Float alpha] ) </h3>
<p>
[page:Color color] - color to converge on.<br />

Linearly interpolates this color's HSL values toward the HSL values of the passed argument.
It differs from the classic [page:.lerp] by not interpolating straight from one color to the other,
but instead going through all the hues in between those two colors.
The alpha argument can be thought of as the ratio between the two colors, where 0.0 is
this color and 1.0 is the first argument.
</p>

<p>
Adds the given [page:Float h], [page:Float s], and [page:Float l] to this color's values.
Internally, this converts the color's [page:.r r], [page:.g g] and [page:.b b] values to HSL, adds
[page:Float h], [page:Float s], and [page:Float l], and then converts the color back to RGB.
</p>
<h3>[method:Color set]( [param:Color_Hex_or_String value] ) </h3>
<p>
[page:Color_Hex_or_String value] - Value to set this color to.<br /><br />
See the Constructor above for full details of what [page:Color_Hex_or_String value] can be.
Delegates to [page:.copy], [page:.setStyle], or [page:.setHex] depending on input type.
</p>
<h3>[method:Color setHex]( [param:Integer hex] ) </h3>
<p>
[page:Integer hex] — [link:https://en.wikipedia.org/wiki/Web_colors#Hex_triplet hexadecimal triplet] format.<br /><br />
Sets this color from a hexadecimal value.
</p>
<h3>[method:Color setHSL]( [param:Float h], [param:Float s], [param:Float l] ) </h3>
<p>
[page:Float h] — hue value between 0.0 and 1.0 <br />
[page:Float s] — saturation value between 0.0 and 1.0 <br />
[page:Float l] — lightness value between 0.0 and 1.0<br /><br />
Sets color from HSL values.
</p>
<h3>[method:Color setRGB]( [param:Float r], [param:Float g], [param:Float b] ) </h3>
<p>
[page:Float r] — Red channel value between 0.0 and 1.0.<br />

[page:Float b] — Blue channel value between 0.0 and 1.0.<br /><br />
Sets this color from RGB values.
</p>
<h3>[method:Color setScalar]( [param:Float scalar] ) </h3>
<p>
[page:Float scalar] — a value between 0.0 and 1.0.<br /><br />
Sets all three color components to the value [page:Float scalar].
</p>
<h3>[method:Color setStyle]( [param:String style] ) </h3>
<p>
[page:String style] — color as a CSS-style string.<br /><br />
Sets this color from a CSS-style string. For example,
"rgb(250, 0,0)",
"rgb(100%, 0%, 0%)",
"hsl(0, 100%, 50%)",
"#ff0000",
"#f00", or
"red" ( or any [link:https://en.wikipedia.org/wiki/X11_color_names#Color_name_chart X11 color name]
- all 140 color names are supported ).<br />
Translucent colors such as "rgba(255, 0, 0, 0.5)" and "hsla(0, 100%, 50%, 0.5)" are also accepted,
but the alpha-channel coordinate will be discarded.<br /><br />
Note that for X11 color names, multiple words such as Dark Orange become the string 'darkorange' (all lowercase).
</p>
<h3>[method:Color setColorName]( [param:String style] ) </h3>
<p>
[page:String style] — color name ( from [link:https://en.wikipedia.org/wiki/X11_color_names#Color_name_chart X11 color names] ).<br /><br />
Sets this color from a color name. Faster than [page:.setStyle] method if you don't need the other CSS-style formats.<br/><br/>
For convenience, the list of names is exposed in Color.NAMES as a hash: <code>Color.NAMES.aliceblue // returns 0xF0F8FF</code>
</p>
<h3>[method:Color sub]( [param:Color color] ) </h3>
<p>
Subtracts the RGB components of the given color from the RGB components of this color.
If this results in a negative component, that component is set to zero.
</p>
<h3>[method:Array toArray]( [param:Array array], [param:Integer offset] ) </h3>
<p>
[page:Array array] - An optional array to store the color to. <br />
[page:Integer offset] - An optional offset into the array.<br /><br />
Returns an array of the form [ r, g, b ].
