The goal is to allow the color specifications allowed in CSS for ease of use. However that is still some way of and now the formats supported are the following.
Notation | Description | Weight | |
---|---|---|---|
rgb(R, G, B) | Each value R(ed) , G(reen) and B(lue)
is an integer between 0 and 255. |
0 | |
rgba(R, G, B, A) | Same as rgb() but with an additional Alpha value.
The alpha value is a decimal number between 0 and 1. |
1 |
Notation | Description | Weight |
---|---|---|
#RRGGBB | Where each pair of Examples, decimal values to the left and their
hexadecimal translation to the right: |
0 |
#RRGGBBAA | Same as #RRGGBB but with an additional pair for
Alpha . Alpha follows the same convention as
the other values. |
1 |
#RGB | Shorter version of Example: |
0 |
#RGBA | Shorter version of Example: |
1 |
Generate a color that is a blend between two colors using linear interpolation.
ColorUtils.lerp(first, second, blend)
Name | Type | Description |
---|---|---|
start | string | Start color in the transition. Information about supported Color Formats |
end | string | End color in the transition. Information about supported Color Formats |
blend | float | Specifies how much of each color should be used.
Blend 0 will return the start value.
Respectively 1 will return the end color.
A even blend is achieved using 0.5 . |
Type | Description |
string | A new color that is a blend between the colors specified as start and end . |
The start and end colors may be entered using different color formats. The returned collection will however only consist of one color format. What format is chosen is based on the weight of the formats used. The weight that is the heaviest will selected primarily. If weights are equal the one that occurs first will take precedence. Information about each formats weight you can find under the section Color Formats.
var red = "#bb3f3f";
var green = "#3fbb3f";
var blend = 0.5;
var color = ColorUtils.lerp(red, green, blend);
#7d7d3f
Generate a list of colors that transitions between two colors. Could also be described as a linear gradient.
ColorUtils.loop(first, second, steps)
Name | Type | Description |
---|---|---|
start | string | Start color in the transition. Information about supported Color Formats |
end | string | End color in the transition. Information about supported Color Formats |
steps | int | The total number of colors generated for the transition, start and end colors included. The values has to be 2 or greater. |
Type | Description |
array | Collection of colors in string format creating a gradient from start to end color.
The length of the collection will be equal to the number of steps specified.
Position 0 in the collection will be equal to the start color and position steps - 1
will be equal to the end color. |
The start and end colors may be entered using different color formats. The returned collection will however only consist of one color format. What format is chosen is based on the weight of the formats used. The weight that is the heaviest will selected primarily. If weights are equal the one that occurs first will take precedence. Information about each formats weight you can find under the section Color Formats.
var red = "#bb3f3f";
var green = "rgb(63, 187, 63)";
var steps = 30;
var transition = ColorUtils.transition(red, green, steps);
[ #bb3f3f, #b7433f, #b2483f, #ae4c3f, #aa503f, #a6543f, #a1593f, #9d5d3f, #99613f, #95653f, #906a3f, #8c6e3f, #88723f, #83773f, #7f7b3f, #7b7f3f, #77833f, #72883f, #6e8c3f, #6a903f, #65953f, #61993f, #5d9d3f, #59a13f, #54a63f, #50aa3f, #4cae3f, #48b23f, #43b73f, #3fbb3f ]

Generate a list of colors that transitions between multiple colors. Could also be described as a linear gradient.
ColorUtils.transitions(colors, steps)
Name | Type | Description |
---|---|---|
colors | array | Collection of strings describing the colors that should be transitioned. Order of the collection will be the order or transition. Information about supported Color Formats |
steps | int | The total number of colors generated for the transition, each color in the specified collection included. The values has to be at least the length of the collection. |
Type | Description |
array | Collection of colors in string format creating a gradient between each color specified in colors .
The length of the collection will be equal to the number of steps specified.
Position 0 in the collection will be equal to the first color in colors and position steps - 1
will be equal to the last color im colors . |
The colors may be entered using different color formats. The returned collection will however only consist of one color format. What format is chosen is based on the weight of the formats used. The weight that is the heaviest will selected primarily. If weights are equal the one that occurs first will take precedence. Information about each formats weight you can find under the section Color Formats.
var red = "#bb3f3f";
var green = "#3fbb3f";
var blue = "rgba(63, 63, 187, 1)";
var colors = [red, green, blue];

Generate a list of colors that loops between two colors. Can be used for a constant rotation between two colors.
ColorUtils.transitions(colors, steps)
Name | Type | Description |
---|---|---|
first | string | First color in the transition. Information about supported Color Formats |
second | string | Second color in the transition. Information about supported Color Formats |
steps | int | The total number of colors generated for the transition, each color in the specified collection included. The values has to be at least the length of the collection. |
Type | Description |
array | Collection of colors in string format creating a loop between first to second color.
With two transitions, one from first to second and then one that does the reverse.
The length of the collection will be equal to the number of steps specified. |
The specified colors will only be present once in the loop. No repetition of color means that it will become a smooth rotation when looped.
The colors may be entered using different color formats. The returned collection will however only consist of one color format. What format is chosen is based on the weight of the formats used. The weight that is the heaviest will selected primarily. If weights are equal the one that occurs first will take precedence. Information about each formats weight you can find under the section Color Formats.
var red = "#bb3f3f";
var green = "#3fbb3f";
var steps = 30;
var loop = ColorUtils.loop(red, green, steps);
