I can't add color3

Callum_Cloth · January 9, 2023, 1:35am

I want to add a 15 percent red tint on part but it wont let me
line of code it errors on

workspace.Bottom.Color = Color3.fromRGB(workspace.Bottom.Color + 15 ,0,0)

the error:

attempt to perform arithmetic (add) on Color3 and number

Index the red value of the color:
workspace.Bottom.Color.R + 15

I tried that at first but it errored with (mul) instead of (add)

Sorry, forgot to say that you need to multiply the value by 255 and round it.
math.round((workspace.Bottom.Color.R * 255) + 15)

i replaced it but nothing happens nothing n output either

EgizianoEG · January 9, 2023, 1:45am

Hmm…
Did you place that line alone?
I meant to replace that piece of code only.

This si the whole section of the script

Look, this line should be like the following:

workspace.Bottom.Color = Color3.fromRGB(math.round((workspace.Bottom.Color.R * 255) + 15), 0, 0)

it worked, but the whole part turned red instead of just a tint

EgizianoEG · January 9, 2023, 1:49am

Are you trying to add 15 to all the values of the color?

Callum_Cloth · January 9, 2023, 1:50am

No i want to make it 15 percent more red

EgizianoEG · January 9, 2023, 1:55am

So, you just need to get the other values: green and blue then multiply them by 255.

Here is what it should be:

local Red, Green, Blue = workspace.Bottom.Color.R, workspace.Bottom.Color.G, workspace.Bottom.Color.B
workspace.Bottom.Color = Color3.fromRGB(math.clamp(math.round(workspace.Bottom.Color.R * 255) + 15, 0, 255), math.round(Green * 255), math.round(Blue * 255))

math.clamp is used to make sure that the red value doesn’t go above 255.

It worked!! Thank you for helping, i couldn’t understand any other posts similar to this one

EgizianoEG · January 9, 2023, 2:09am

Hey,

I recommend you use this code instead:

local Red, Green, Blue = workspace.Bottom.Color.R, workspace.Bottom.Color.G, workspace.Bottom.Color.B
workspace.Bottom.Color = Color3.new(math.clamp(Red + (15 / 255), 0, 1), Green, Blue)

That won’t require to convert the color values to RGB and more readable.
