I wanted to give the scripts which called symmetryHueShift.lua the option to choose whether or not to change the colors, without impacting scripts that weren't updated. This appears to work, although sometimes it takes a couple of draw attempts for the change to actually take place

-- Contents of SymmetryHueShift.lua
local SymmetryHueShift = {}

-- Add parameters for hue shift frequency and amount
local hueShiftFrequency = 1
local hueShiftAmount = 0.1

-- Generate a series of colors based on the initial HSV color and the specified number of copies
function SymmetryHueShift.generate(copies, initialHsv, changeColor)
    -- Set default behavior for changeColor if not provided
    if changeColor == nil then
        changeColor = 1  -- Default to 1 (true)
    end

    Symmetry.ClearColors()
    if changeColor == 1 and hueShiftAmount > 0 then
        for i = 0, copies - 1 do
            local t = i / copies
            local newHue = Waveform:Triangle(t, hueShiftFrequency) * hueShiftAmount
            local newColor = Color.HsvToRgb(initialHsv.x + newHue, initialHsv.y, initialHsv.z)
            Symmetry.AddColor(newColor)
        end
        Brush.ForceNewStroke()
    end
end

return SymmetryHueShift

local SymmetryHueShift = {}

local hueShiftFrequency = 1
local hueShiftAmount = 0.1

-- Generate a series of colors based on the initial HSV color and the specified number of copies

    end

    Symmetry.ClearColors()

            local t = i / copies
            local newHue = Waveform:Triangle(t, hueShiftFrequency) * hueShiftAmount
            local newColor = Color.HsvToRgb(initialHsv.x + newHue, initialHsv.y, initialHsv.z)
            Symmetry.AddColor(newColor)
        end
        Brush.ForceNewStroke()
    end
end

return SymmetryHueShift
