How would you use a table to create a brick color change script?

To get the value of the table, you put this "[]" square brackets next to the name of the table. For example, if you table is named colorTable then you will do colorTable[]. Inside of the square bracket, you will input the index of the wanted value. So, if you are trying to get the random number, put math.random() inside the square bracket.

local colorTable = {
--[[Index = 1, Value = ]]   "Really Red",
--[[Index = 2, Value = ]]   "Really Blue",
--[[Index = 3, Value = ]]   "New Yeller",
--[[Index = 4, Value = ]]   "Dark Green"
}

while wait() do
    local randomIndex = math.random(1,#colorTable)
    workspace.Baseplate.BrickColor = BrickColor.new(colorTable[randomIndex]
end

The reason inputting the index of the table returns the value is because the index is the address of the value. For example, the first value which is "Really Red" lives in address colorTable[1].

Also, in the while loop code, I includedlocal randomIndex = math.random(1,#colorTable). What the hashtag means is that when this is next to the table, it will count how many index there is inside the table. so in my example, I did #colorTable which will return 4 since there is 4 sets of data stored inside the table.

Now, that the random index is made, all it does is the script will index the value from the table. if the randomIndex returns 3, the value of colorTable[randomIndex] will be "New Yeller"

I hope my example gave you some idea of how you can use table. Good luck on your script :D

Here's my solution, I typed it up so I might as well provide. I'm not good at explaining things.

baseplate = workspace:FindFirstChild("Baseplate")

colors = {
"Really red",
"Baby blue", 
"Sage green", 
"Bright yellow", 
"Neon orange"
}

while true do
    local var = math.random(1,#colors)
    if baseplate then
    baseplate.BrickColor = BrickColor.new(colors[var])
    end
    wait(0.5)
end

Probably not what you're looking for but, here's a script.

local Baseplate = game.Workspace:FindFirstChild("Baseplate")
local Colors = {

c1 = BrickColor.new("Really red"),

c2 = BrickColor.new("Baby blue"),

c3 = BrickColor.new("Sage green"),

c4 = BrickColor.new("Bright yellow"),

c5 = BrickColor.new("Neon orange")


}
while true do
   Baseplate.BrickColor = Colors.c1
   wait(0.5)
   Baseplate.BrickColor = Colors.c2
   wait(0.5)
   Baseplate.BrickColor = Colors.c3
   wait(0.5)
   Baseplate.BrickColor = Colors.c4
   wait(0.5)
   Baseplate.BrickColor = Colors.c5
   wait(0.5)
end
