How do I make colors change smoothly without tweening?

I’m tweening the color of many parts, using tweenservice for this is very laggy and unoptimized, how would I change the color of the parts without the use of tweens?

Use lerping (linear interpolation)

Did you use the :Lerp method on the Color3?
example use:

local duration = 2 -- Duration
local elapsed = 0
local parts = {part1, part2, part3} -- Replace with your parts

local function lerpColor(startColor, endColor, alpha)
    return startColor:Lerp(endColor, alpha)
end

while elapsedTime < duration do
    local alpha = elapsed / duration
    local currentColor = lerpColor(startColor, endColor, alpha)

    for _, part in ipairs(parts) do
        part.Color = currentColor
    end

    elapsed = elapsed + game:GetService("RunService").Heartbeat:Wait()
end

Yeah, you might not be doing it right. If you want to keep colours the same brightness, you can lerp the hue value of a HSV colour, or otherwise use the :Lerp() function of Color3 like @VonsRevenges suggested.

Basic lerping function 
local function lerp(startVal: number, endVal: number, alpha: number): number
    return startVal + (endVal - start) * alpha
end
