Look up a colorLook up one color: its CSS name when it is one of the named colors, the same color in hex, rgb and hsl with its components, the black or white text that reads on it, and its complementary and grayscale, each described the same way. Give it the color as a name, a hex code, rgb or hsl, with an alpha channel if it has one. A malformed color is refused here with a message saying what a color looks like.
Convert a colorConvert one color into hex, rgb or hsl and get the converted value as a string ready to paste into a stylesheet, a design tool or a message. A color with an alpha channel converts with it, so rgba(196, 65, 90, 0.47) becomes #C4415A78, and the value without the alpha comes back beside it. The full color comes back too, with its name and every component.
Get the text color for a backgroundFind out whether black or white text reads better on a color, for a badge, a button or a label whose background comes from data. Serialif Color decides by the color's perceived brightness: white on a dark color, black on a light one, judged without any alpha channel.
Get the complementary colorGet a color's complementary: its negative, which Serialif Color makes by inverting each rgb channel, so the hue turns half way round the color wheel and the lightness is mirrored. Any alpha channel is kept. It comes back described in full, with its CSS name when it has one and the text color the service pairs with it.
Get the grayscale version of a colorGet a color in grayscale: the same hue and lightness with the saturation taken to 0, the gray it prints as in black and white. Any alpha channel is kept. It comes back described in full, with its CSS name when it has one and the text color the service pairs with it.
Look up several colorsLook up a list of colors in one step, up to 10 at a time, in the order given: a brand palette, the colors in a design file, the swatches in a spreadsheet column. Each is looked up as Look up a color does, one request each, and the hex codes, names and text colors come back as plain lists beside the full records. Every entry is checked before the first request is made, so a malformed one fails the step without spending requests on the good ones ahead of it.
Get a random colorPick an opaque color at random and look it up, for an accent, a label or a placeholder that should not be the same every time. Add a seed to make the pick repeatable: the same seed always gives the same color, so naming a customer, a project or a date here gives each its own color that a later run finds again. Its complementary and grayscale come back too.
Check service statusCheck whether Serialif Color is answering, and how quickly. This is the one action that reports a problem as a value instead of failing the step, so a workflow can decide what to do about it.
