Is there a fancy object in ROBLOX Studio to transmit from 1 color to another smoothly?

Lerp

You can use the lerp function on Color3 datatypes. "Lerp" is short for "Linear Interpolation", and takes in 2 arguments:

• Color3 end goal: What you're trying to get to

• Number alpha: Number between 0 and 1, acting as a percentage between start and end

Usage

Since you're looking for a smooth transition, you should use a numerical for loop. Syntax looks like this:

for [var] = [start],[finish],[(optional) increment] do

[code]

end

Use your color goal as the first argument in the Lerp function, and then your [var] divided by your [finish] to indicate a gradual climb.

Code

local part = workspace.Part --This is your part
local color = Color3.new(0,0,0) --This is the desired color; black
local smooth = 20 --This is how smooth the transition will be

for i = 1,smooth do
    local c = part.BrickColor.Color:lerp(color,i/smooth); --Aquire the color
    print(BrickColor.new(c.r,c.g,c.b));
    part.BrickColor = BrickColor.new(c.r,c.g,c.b) --Convert to BrickColor
    wait(.05)
end

Note: BrickColors and Color3s do not translate perfectly. You may notice some odd colors pop up but for the most part, the transition is normal.

You could try this, a Color3 lerp function. For example,

local start = Color3.new(1,1,1)-- White
local End = Color3.new(0,0,0)--Black

for i = 0,1,0.03 do
    wait()
    local color = start:lerp(End,i)
end

1. Make the brick white
2. Place black decals around the brick
3. Comment to me if you don't know how to make a smoothly decal transparency & I edit my answear
