Colors (API)

The Colors API allows you to manipulate sets of colors. This is useful in conjunction with Bundled Cables from the RedPower mod, RedNet Cables from the MineFactory Reloaded mod, and colors on Advanced Computers and Advanced Monitors.

For the non-American English version just replace 'colors' with 'colours' and it will use the other API, colours—which is exactly the same, except in non-American English (e.g. gray is spelt grey and lightGray is spelt lightGrey).

Colors (API)
Function	Return values	Description
colors.combine(number color1, number color2, ...)	number value	Combines one or more colors (or sets of colors) into a larger set.
colors.subtract(number colors, number color1, number color2, ...)	number value	Removes one or more colors (or sets of colors) from an initial set.
colors.test(number colors, number color)	boolean contained	Tests whether color is contained within colors.

Note: The standard addition (+) and subtraction (-) operators while able to be used on colors instead of colors.combine and colors.subtract should be avoided due to the nature of the colour format. For example

print(colors.white + colors.white)

will output 2 which is orange as opposed to

print(colors.combine(colors.white, colors.white))

will output 1 which is white.

Furthermore, the Bit (API) may be used on sets of colors. For example,

bCableLeft  = rs.getBundledInput("left")
bCableRight = rs.getBundledInput("right")

-- Get a number representing colors on in both right and left bundled cables
commonColors    = bit.band(bCableLeft, bCableRight)

-- Get all the colors active on either right or left
totalColors     = bit.bor(bCableLeft, bCableRight)

-- Get the colors which are active on right, or left, but not both at the same time
exclusiveColors = bit.bxor(bCableLeft, bCableRight)

-- Get the colors that are not active on the left
offColorsA      = bit.bnot(bCableLeft)

Colors

The following table includes; the variable name to use in ComputerCraft programs, the decimal, hexadecimal, and binary values of the color, the number used in the 'paint' programs save files, and the actual color used to display in the ComputerCraft mod (provided in web hexadecimal format).
