Changing my colour wheel to use RGB

Help and Feedback Scripting Support
#1

I picked up this color wheel

local colourWheel = script.Parent:WaitForChild("ColourWheel")
local wheelPicker = colourWheel:WaitForChild("Picker")

local darknessPicker = script.Parent:WaitForChild("DarknessPicker")
local darknessSlider = darknessPicker:WaitForChild("Slider")

local colourDisplay = script.Parent:WaitForChild("ColourDisplay")

local uis = game:GetService("UserInputService")

local buttonDown = false
local movingSlider = false
local active = script.Parent.Parent.Parent.Parent.Properties.CustomColor

local currentColor = Color3.new(1, 1, 1) 

local function updateColour(centreOfWheel)
	local colourPickerCentre = Vector2.new(
		colourWheel.Picker.AbsolutePosition.X + (colourWheel.Picker.AbsoluteSize.X / 2),
		colourWheel.Picker.AbsolutePosition.Y + (colourWheel.Picker.AbsoluteSize.Y / 2)
	)
	local h = (math.pi - math.atan2(colourPickerCentre.Y - centreOfWheel.Y, colourPickerCentre.X - centreOfWheel.X)) / (math.pi * 2)
	local s = (centreOfWheel - colourPickerCentre).Magnitude / (colourWheel.AbsoluteSize.X / 2)
	local v = math.abs((darknessSlider.AbsolutePosition.Y - darknessPicker.AbsolutePosition.Y) / darknessPicker.AbsoluteSize.Y - 1)

	local hsv = Color3.fromHSV(math.clamp(h, 0, 1), math.clamp(s, 0, 1), math.clamp(v, 0, 1))

	currentColor = hsv

	colourDisplay.ImageColor3 = hsv
	darknessPicker.UIGradient.Color = ColorSequence.new{
		ColorSequenceKeypoint.new(0, hsv),
		ColorSequenceKeypoint.new(1, Color3.new(0, 0, 0))
	}
end

colourWheel.MouseButton1Down:Connect(function()
	buttonDown = true
end)

darknessPicker.MouseButton1Down:Connect(function()
	movingSlider = true
end)

uis.InputEnded:Connect(function(input)
	if input.UserInputType ~= Enum.UserInputType.MouseButton1 then return end
	buttonDown = false
	movingSlider = false
end)

uis.InputChanged:Connect(function(input)
	if input.UserInputType ~= Enum.UserInputType.MouseMovement then return end

	local mousePos = uis:GetMouseLocation() - Vector2.new(0, game:GetService("GuiService"):GetGuiInset().Y)

	local centreOfWheel = Vector2.new(colourWheel.AbsolutePosition.X + (colourWheel.AbsoluteSize.X / 2), colourWheel.AbsolutePosition.Y + (colourWheel.AbsoluteSize.Y / 2))

	local distanceFromWheel = (mousePos - centreOfWheel).Magnitude

	if distanceFromWheel <= colourWheel.AbsoluteSize.X / 2 and buttonDown then
		wheelPicker.Position = UDim2.new(0, mousePos.X - colourWheel.AbsolutePosition.X, 0, mousePos.Y - colourWheel.AbsolutePosition.Y)
	elseif movingSlider then
		darknessSlider.Position = UDim2.new(darknessSlider.Position.X.Scale, 0, 0, 
			math.clamp(
				mousePos.Y - darknessPicker.AbsolutePosition.Y, 
				0, 
				darknessPicker.AbsoluteSize.Y)
		)
	end

	updateColour(centreOfWheel)
end)

local function getRGBColor()
	return currentColor
end


game:GetService("RunService").Heartbeat:Connect(function()
	if active.Value == true then
		script.Parent.Parent.Parent.Parent.Color.Fade.ColorText.Text = "Custom"
		active.Parent.Color.Names.Value = "Custom"

		active.Parent.Color.Value = getRGBColor()
		local R, G, B = active.Parent.Color.Value.R * 255, active.Parent.Color.Value.G * 255, active.Parent.Color.Value.B * 255

		R = math.floor(R + 0.5)
		G = math.floor(G + 0.5)
		B = math.floor(B + 0.5)

		local text = script.Parent.TextLabel
		text.Text = R .. ", " .. G .. ", " .. B

		if R == 3 and G == 3 and B == 3 then
			active.Parent.Color.Value = Color3.fromRGB(0, 0, 0)
		end

		script.Parent.Parent.Parent.Parent.Color.Fade.ColorPreview.BackgroundColor3 = Color3.fromRGB(R, G, B)
	end
end)

from a tutorial channel, and I slightly modified it.
Now, right now I am making a system where you can set a part’s properties by just pressing Alt. The issue is though, this uses HSV while my system uses RGB.

How could I convert it, and set the position of the pointer on the colour wheel dynamically as well when setting it?
[When the functions called it sets the CurrentColor property, the position of the dot on the colour wheel and the little slider]

wait, do you want to figure out how to convert HSV to RGB, or are you turning this into color wheel into rgb

edit: read your post again, and figured out what you mean

local function hsvToRGB(h,s,v)
	local c3 = Color3.fromHSV(h,s,v);
	return c3.R, c3.G, c3.B; 
end
