ChromaPulse
One time purchase and 5 times trial.

“ChromaPulse” is an image color analysis plugin of Figma,
that extracts dominant and prominent colors from nodes
which are filled with an image and generates palettes.
Multi Process
Up to 10 images can be analyzed at once.

Algorithm
-
Dominant Color
The palette is generated by analyzing the full range of colors that dominate the image.
The extraction method is based on the median cut quantization (MMCQ) algorithm used by color-thief.
-
Prominent Color
Extracts mainly the distinctive colors of an image, yielding results that are slightly more pointed than dominant colors.
This is a simple mechanical extraction method by color.js.
-
Average Color
Obtains the average color of the image.
*Notwithstanding the number of palettes specified, the result obtained from average color extraction is only one color.
Granularity
This is a specification of the scan granularity during image analysis.
The finer the granularity, the slower the processing speed will be because of
the increased processing load, larger granularities result in faster processing speeds.
A finer granularity does not necessarily mean better results,
this should be considered as an option that changes the extraction variation of the palette.
And it has a greater impact on the extraction of prominent colors.
