Introduction
This template contains several methods for manipulating color values:
- Color darkening/lightening (operating lightness)
- Modify color saturation
- Invert color
- Add opacity
- random color
- Mix two colors
And two judgment methods:
- Determine whether the color is bright
- Determine whether the color is dark
Usage
All methods of this template support passing in color values in these formats only: hex color (well number plus 6 hex digits), hex abbreviated color (well number plus 3 hex digits), rgb function, rgba function, hsl function, hsla function, css color keyword.
In addition to adding transparency, the output format of the function is hex color. Please also note that the "Infobox" series templates only support hex colors.
The {{{color_block}} template used in the following example is used to display colors.
Operate the lightness and saturation of the color
is controlled via the first parameter.
A typical usage scenario for this method is to use it to derive the colors for each section (title, group, list, etc.) after selecting the main color for the large family of templates.
{{ColorOps|properties (optional) operator operation value|color value}}
- Attributes.
- Default: the reverse operation brightness (i.e., + is to decrease the brightness, - is to increase the brightness. For ease of memory you can read the defaults as "darken" and "lighten") Template:BlackoutTemplate:Black screen
- l: manipulates the brightness, if the brightness increases, the color will be white and vice versa
- s: operate saturation, saturation increases the color becomes more vivid, and vice versa gradually tends to gray
- Operators: + and -, which can be interpreted as corresponding properties to raise and lower
- operation value: an integer between 1 ~ 100, the default is 10
Chestnut one
Chestnut II
Note that while the color preview is an integer multiple, the optional range is arbitrary between 0 and 100.
Invert
{{ColorOps|reverse|color values}}
Chestnuts.
Before inversion: {{color_block|#FF8040}}
After inversion: {{color_block|{{ColorOps|reverse|#FF8040}}}}
</pre
Before inversion: {{color_block|#FF8040}}
After inversion: {{{color_block|{{ColorOps|reverse|#FF8040}}}}
=== Add opacity ===
The return value there uses the rgba function of css. The opacity range is from 0 to 1.
