blue = script.Parent.B
yellow = script.Parent.Y
red = script.Parent.R
green = script.Parent.G

while true do
script.Parent.Part =  'red'
wait(6)
blue.Transparency = 1
blue.CanCollide = false

yellow.Transparency = 1
yellow.CanCollide = false

green.Transparency = 1
green.CanCollide = false
wait(10)
blue.Transparency = 0
blue.CanCollide = true

yellow.Transparency = 0
yellow.CanCollide = true

green.Transparency = 0
green.CanCollide = true

script.Parent.Part = 'BLUE'
wait(6)
red.Transparency = 1
red.CanCollide = false
	
yellow.Transparency = 1
yellow.CanCollide = false

green.Transparency = 1
green.CanCollide = false
wait(10)	
yellow.Transparency = 0
yellow.CanCollide = true

red.Transparency = 0
red.CanCollide = true

green.Transparency = 0
green.CanCollide = true

script.Parent.Part = 'GREEN'
wait(6)

red.Transparency = 1
red.CanCollide = false

blue.Transparency = 1
blue.CanCollide = false

yellow.Transparency = 1
yellow.CanCollide = false

wait(10)
red.Transparency = 0
red.CanCollide = true

blue.Transparency = 0
blue.CanCollide = true

yellow.Transparency = 0
yellow.CanCollide = true

 script.Parent.Part = 'YELLOW'
wait(6)

red.Transparency = 1

end

Try this script. Tell me if it doesn't work! I didn't test it yet.

local blue = script.Parent.B
local yellow = script.Parent.Y
local red = script.Parent.R
local green = script.Parent.G

local Text = script.Parent.SurfaceGui.TextLabel.Text
local TextProperties = script.Parent.SurfaceGui.TextLabel
TextProperties.RichText = true
TextProperties.TextScaled = true

local TextColor = script.Parent.SurfaceGui.TextLabel.TextColor3
SimonSays = true

local WaitTime = math.random(6,10) --math.random will pick a number between A and B, Minimum and Maximum, This will come in handy to make random times.

while true do
    if SimonSays == true then
        local Roll = math.random(1,4) --Rolling Dice, This picks what it'll show.

        if Roll == 1 then
            Text = "Red"
            TextColor = Color3.fromRGB(255,0,0)
            wait(WaitTime)
            blue.Transparency = 0 and blue.CanCollide = false
            yellow.Transparency = 0 and yellow.CanCollide = false
            green.Transparency = 0 and green.CanCollide = false
        end

        if Roll == 2 then
            Text = "Green"
            TextColor = Color3.fromRGB(0,255,0)
            wait(WaitTime)
            blue.Transparency = 0 and blue.CanCollide = false
            yellow.Transparency = 0 and yellow.CanCollide = false
            red.Transparency = 0 and red.CanCollide = false
        end

        if Roll == 3 then
            Text = "Blue"
            TextColor = Color3.fromRGB(0,0,255)
            wait(WaitTime)
            green.Transparency = 0 and green.CanCollide = false
            yellow.Transparency = 0 and yellow.CanCollide = false
            red.Transparency = 0 and red.CanCollide = false
        end

        if Roll == 4 then
            Text = "Yellow"
            TextColor = Color3.fromRGB(255,255,0)
            wait(WaitTime)
            green.Transparency = 0 and green.CanCollide = false
            blue.Transparency = 0 and blue.CanCollide = false
            red.Transparency = 0 and red.CanCollide = false
        end
    end
end
