Color Harmony provides methods useful for color combination discovery.
_adjustOffsetAndFinishcolor
offsets
to
Takes an HSL array, and an array of offsets and returns and array of colors that have been adjusted. The returned colors will match the array of offsets provided. If you wish you have the same color value returned, you can provide null or an empty object to the offsets. The returned array will contain color value strings that have been adjusted from subtractive to additive.
_constrainHuehue
[precision]
Contrain the hue to a value between 0 and 360 for calculations and real color wheel value space. Provide a precision value to round return value to a decimal place
Constrained hue value
_finishhsla
[to]
Converts the provided HSLA values from subtractive to additive returning a converted color string
_searchLuminanceForBrightnesscolor
brightness
min
max
Calculates the luminance as a mid range between the min and max to match the brightness level provided
Found luminance to achieve requested brightness
_startstr
Converts the provided color from additive to subtractive returning an Array of HSLA values
str
String
_toAdditivehue
Adjusts the hue degree from subtractive to additive
hue
Number
Converted additive hue
_toSubtractivehue
Adjusts the hue degree from additive to subtractive
hue
Number
Converted subtractive hue
getAnalogousstr
[offset]
[to]
Returns an Array of five colors. The first color in the Array will be the color passed in. The remaining four will be analogous colors two in either direction from the initially provided color.
getBrightnessstr
Returns 0 - 100 percentage of brightness from 0 (black) being the
darkest to 100 (white) being the brightest.
str
String
getComplementarystr
[to]
Returns an Array of two colors. The first color in the Array will be the color passed in. The second will be the complementary color of the color provided
getMonochromestr
[count]
[to]
Calculates lightness offsets resulting in a monochromatic Array of values.
getOffsetstr
adjust
[to]
Adjusts the provided color by the offset(s) given. You may adjust hue, saturation, and/or luminance in one step.
getSimilarstr
[offset]
[count]
[to]
Creates an Array of similar colors. Returned Array is prepended with the color provided followed a number of colors decided by count
getSimilarBrightnessstr
match
[to]
Returns a new color value with adjusted luminance so that the
brightness of the return color matches the perceived brightness
of the match color provided.
getSplitstr
[offset]
[to]
Returns an Array of three colors. The first color in the Array will be the color passed in. The second two will be split complementary colors.
getSquarestr
[to]
Returns an Array of four colors. The first color in the Array will be the color passed in. The remaining three colors are equidistant offsets from the starting color and each other.
getTetradstr
[offset]
[to]
Returns an Array of four colors. The first color in the Array will be the color passed in. The remaining three colors are equidistant offsets from the starting color and each other.
_brightnessWeightsBrightness weight factors for perceived brightness calculations
"standard" values are listed as R: 0.241, G: 0.691, B: 0.068 These values were changed based on grey scale comparison of hsl to new hsl where brightness is said to be within plus or minus 0.01.
