How to use color picker frame in slash command?

[x2infinity]

Im trying to change the colour of a texture using the Color picker frame

This is my current slash command I'd like to replace with the color picker

-- Slash command to change color
SLASH_COLORCHANGE1 = "/starcolour"
SlashCmdList["COLORCHANGE"] = function(msg)
    local r, g, b = strsplit(" ", msg)
    r, g, b = tonumber(r), tonumber(g), tonumber(b)
    if r and g and b then
        local alpha = StarCursor.texture:GetAlpha()
        StarCursor.texture:SetVertexColor(r, g, b, alpha)
        StarCursorSettings.r, StarCursorSettings.g, StarCursorSettings.b = r, g, b
    end
end

-- Slash command to open color picker
SLASH_COLORPICKER1 = "/starcolour"
SlashCmdList["COLORPICKER"] = function()
    ColorPickerFrame:SetupColorPickerAndShow({
        r = StarCursorSettings.r,
        g = StarCursorSettings.g,
        b = StarCursorSettings.b,
        opacity = StarCursorSettings.alpha,
        hasOpacity = true,
        swatchFunc = function()
            local r, g, b = ColorPickerFrame:GetColorRGB()
            StarCursor.texture:SetVertexColor(r, g, b, a)
            StarCursorSettings.r, StarCursorSettings.g, StarCursorSettings.b, StarCursorSettings.alpha = r, g, b, a
        end,
        cancelFunc = function()
            -- Do nothing on cancel
        end
    })
end

If I change the color on the wheel and then cancel, it doesnt revert the color it just stays how it was selected on the wheel.

-- dummy saved settings
local StarCursorSettings = { r=1, g=1, b=1, opacity=1, }
 
-- dummy frame and texture
local StarCursor = CreateFrame("Frame")
StarCursor:SetSize(20, 20)
StarCursor:SetPoint("TOP")
StarCursor.texture = StarCursor:CreateTexture()
StarCursor.texture:SetAllPoints()
StarCursor.texture:SetColorTexture(1, 1, 1)
 
-- change the colour and save settings
local function SwatchFunction()
    local r, g, b  = ColorPickerFrame:GetColorRGB()
    local opacity = ColorPickerFrame:GetColorAlpha()
    StarCursor.texture:SetVertexColor(r, g, b, opacity)
    StarCursorSettings.r, StarCursorSettings.g, StarCursorSettings.b, StarCursorSettings.opacity = r, g, b, opacity
end
 
-- reset colour on cancel and save settings
local function CancelFunction()
    local color = ColorPickerFrame.previousValues
    StarCursor.texture:SetVertexColor(color.r, color.g, color.b, color.a)
    StarCursorSettings.r, StarCursorSettings.g, StarCursorSettings.b, StarCursorSettings.opacity = color.r, color.g, color.b, color.a
end
 
-- slash command
SLASH_COLORPICKER1 = "/starcolour"
SlashCmdList["COLORPICKER"] = function(msg)
    local cpSettings = {}
    for k, v in pairs(StarCursorSettings) do
        cpSettings[k] = v
    end
    cpSettings.hasOpacity = true
        cpSettings.swatchFunc = SwatchFunction
        cpSettings.cancelFunc = CancelFunction
    ColorPickerFrame:SetupColorPickerAndShow(cpSettings)
end

Thanks I did figure out a solution:

SLASH_COLORPICKER1 = "/starcolour"
SlashCmdList["COLORPICKER"] = function()
    local prevr, prevg, prevb, preva = StarCursor.texture:GetVertexColor()
    StarCursor.texture:Show();
    ColorPickerFrame:SetupColorPickerAndShow({
        r = StarCursorSettings.r,
        g = StarCursorSettings.g,
        b = StarCursorSettings.b,
        opacity = StarCursorSettings.alpha,
        hasOpacity = true,
        swatchFunc = function()
            local r, g, b = ColorPickerFrame:GetColorRGB()
            local a = ColorPickerFrame:GetColorAlpha()
            StarCursor.texture:SetVertexColor(r, g, b, a)
            StarCursorSettings.r, StarCursorSettings.g, StarCursorSettings.b, StarCursorSettings.alpha = r, g, b, a
        end,
        cancelFunc = function()
            StarCursor.texture:SetVertexColor(prevr, prevg, prevb, preva)
            StarCursorSettings.r, StarCursorSettings.g, StarCursorSettings.b, StarCursorSettings.alpha = prevr, prevg, prevb, preva
        end
    })
end
