In Auto.js, there are two ways to represent a color.

One way is a string "#AARRGGBB" or "#RRGGBB", where:

• AA is the alpha channel (opacity)
• RR is red
• GG is green
• BB is blue

For example, "#ffffff" means white, and "#7F000000" means semi-transparent black.

Another way is a hexadecimal 32-bit integer 0xAARRGGBB, for example:

• 0xFF112233 represents "#112233"
• 0x11223344 represents "#11223344"

You can convert a color integer to a string with colors.toString(), and parse a color string into an integer with colors.parseColor().

colors.toString(color)

• color {number} Color integer
• Returns {string}

Returns the color as a string in the "#AARRGGBB" format.

colors.red(color)

• color {number | string} Color value
• Returns {number}

Returns the red channel value of color, range 0 ~ 255.

colors.green(color)

• color {number | string} Color value
• Returns {number}

Returns the green channel value of color, range 0 ~ 255.

colors.blue(color)

• color {number | string} Color value
• Returns {number}

Returns the blue channel value of color, range 0 ~ 255.

colors.alpha(color)

• color {number | string} Color value
• Returns {number}

Returns the alpha channel value of color, range 0 ~ 255.

colors.rgb(red, green, blue)

• red {number} Red channel value
• blue {number} Green channel value
• green {number} Blue channel value
• Returns {number}

Returns the integer color composed by these channels. Alpha is fixed to 255 (opaque).

colors.argb(alpha, red, green, blue)

• alpha {number} Alpha channel value
• red {number} Red channel value
• green {number} Green channel value
• blue {number} Blue channel value
• Returns {number}

Returns the integer color composed by these channels.

colors.parseColor(colorStr)

• colorStr {string} Color string, e.g. "#112233"
• Returns {number}

Returns the color as an integer value.
