How would I get RGB from Color3

Help and Feedback Scripting Support

I’m basically just wanting to get the RGB from a parts BackgroundColor3 and print it but for some reason this only prints 0,0,0.

This is what I have so far.

	local BGColor = part.BackgroundColor3
	print(Color3.fromRGB(child.BackgroundColor3))
Color3 Object returning HSV instead of RGB

Color3 by default prints in Color3.new() form.

If you wish to print the RGB version, you’d do something more like this.

local childBGColor = child.BackgroundColor3
print(childBGColor.R* 255 ..", "..childBGColor.G * 255 ..", "..childBGColor.B * 255)

This will not be 100% accurate due to floating point errors, you will likely need to round.

Ah I see that’s great I did see something about that. How would I round it?

You can use the math.round function from Roblox to round these RGB values to what you’d like after you scale them by 255 as @pwrcosmic explained.

#5 
local function c3ToRGB(c3: Color3): {R: number, G: number, B: number}
  return {
    R = math.floor(c3.R * 255)
    G = math.floor(c3.G * 255)
    B = math.floor(c3.B * 255)
  }
}

It’s also doable with the ToHex if you want to avoid rounding:

local function color3ToRGB(color)
	if typeof(color) == 'Color3' then
		local hex = color:ToHex()
		
		local r = tonumber('0x'..string.sub(hex,1,2))
		local g = tonumber('0x'..string.sub(hex,3,4))
		local b = tonumber('0x'..string.sub(hex,5,6))
		
		return r, g, b
	end
end

--[[
	Example:
	local part = workspace.Baseplate
	print(color3ToRGB(part.Color))        -- 99 95 98

	local r,g,b = color3ToRGB(part.Color)
	print(r,g,b)         -- 99 95 98
]]

why are you making a color3 from a color3

Color3.R, Color3.G, Color3.B in order to get the RGB components of a “Color3” value.

Why are you using floor instead of round?
