= Material Convertor Nodes =
As the name implies, these nodes convert the colors in the material in some way.

== ColorRamp Node ==
[[Image:26-Manual-Material-Convertor-Node-ColorRamp.png|frame|right|{{Literal|ColorRamp}} node]]
The ColorRamp Node is used for mapping values to colors with the use of a gradient. It works exactly the same way as a [[Doc:2.6/Manual/Materials/Properties/Ramps|Colorband for textures and materials]], using the Factor value as a slider or index to the color ramp shown, and outputting a color value and an alpha value from the output sockets.

By default, the ColorRamp is added to the node map with two colors at opposite ends of the spectrum. A completely black black is on the left (Black as shown in the swatch with an Alpha value of 1.00) and a whitewash white is on the right.

To select a color, {{Shortcut|LMB}} click on the thin vertical line/band within the colorband. The example picture shows the black color selected, as it is highlighted white. The settings for the color are shown above the colorband as (left to right): color swatch, Alpha setting, and interpolation type.

==Separate RGB Node==

[[File:26-Manual-Material-Convertor-Node-SeparateRGB.png|frame|right|{{Literal|Separate RGB}} node]]

===Inputs===

;{{Literal|Image}}
: Input color value. Includes a color swatch, allowing you to select the color directly on the node.

===Outputs===

==Separate HSV Node==

[[File:26-Manual-Material-Convertor-Node-SeparateHSV.png|frame|right|{{Literal|Separate HSV}} node]]
This node separates an image into image maps for the hue, saturation, value channels. Three values, often considered as more intuitive than the RGB system (nearly only used on computers)

Use and manipulate the separated channels for different purposes; i.e. to achieve some compositing/color adjustment result. For example, you could expand the Value channel (by using the multiply node) to make all the colors brighter. You could make an image more relaxed by diminishing (via the divide or map value node) the Saturation channel. You could isolate a specific range of colors (by clipping the Hue channel via the Colorramp node) and change their color (by the Add/Subtract mix node).

===Inputs===

;{{Literal|Color}}
: Input color value. Includes a color swatch, allowing you to select the color directly on the node.

===Outputs===

;{{Literal|H}}
: Value of the hue color channel, separated out by the node (in some way, choose a «color» of the rainbow).
;{{Literal|S}}
: Value of the saturation color channel, separated out by the node (the ''quantity'' of hue in the color (from desaturate - shade of gray - to saturate - brighter colors)).
;{{Literal|V}}
: Value of the value color channel, separated out by the node (the '''luminosity''' of the color (from 'no light' - black - to 'full light' - 'full' color, or white if Saturation is 0.0)).
{{clr}}

==Combine HSV Node==

[[File:26-Manual-Material-Convertor-Node-CombineHSV.png|frame|right|{{Literal| Combine HSV}} node]]
This node combines a color from separated hue, saturation, value color channels.

===Inputs===

;{{Literal|H}}
: Input value of hue color channel. The value can be provided by another node or set manually.
;{{Literal|S}}
: Input value of saturation color channel. The value can be provided by another node or set manually.
;{{Literal|V}}
: Input value of value color channel. The value can be provided by another node or set manually.

===Outputs===

;{{Literal|Color}}
: Output value of the color, combined by the node.
