# How do you change the background colour of a UI?

SOLVED - Check answers.

I am trying to create a darkening effect on a button when you press on it, similar to that of roblox's AutoButtonColor property. However, when I try to set the background colour (backgroundcolour3), it immediately changes to white, no matter the input in the parameters. Here's my localscript:

local buttons = script.Parent.Buttons
local research = script.Parent.ResearchUI

buttons.Frame.Research.MouseButton1Up:Connect(function()
local debounce = false
buttons.Frame.Research.BackgroundColor3 = Color3.new(232, 189, 136)
if debounce then
wait()
else
if research.Enabled == true then
research.Enabled = false
else
research.Enabled = true
end
end
debounce = true
wait(0.1)
buttons.Frame.Research.BackgroundColor3 = Color3.new(255, 208, 149)
end)


I don't get any errors in console, and everything seems to working completely fine. It happens on both the background color changes. Any suggestions?

Hello, first mistake I see is .MouseButton1Up, instead of .MouseButton1Down, this shouldnt play a role but idk ;( BeautifulAuraLover 371 — 17d

MouseButton1Up works the same way as Down, except up only functions after you stop clicking, so if you're holding the click it won't click. KingDomas 148 — 17d

And I did try .BackgroundColor but that's only brick color so that doesn't work with the RGB values. KingDomas 148 — 17d

Yep, I know I just thought its a mistake because you wrote "when I press on it". Isnt line 18 the white color? BeautifulAuraLover 371 — 17d

If it is, you got too low cooldown there BeautifulAuraLover 371 — 17d

I commented everything inside the on mouse click function except for the first background color change and it still turns white when I click it, so it is something to do with line 6 and 18 on the actual change of color. KingDomas 148 — 17d

I solved it for anyone else who has this and needs to fix it. Since RGB values (Color3) are out of 255, when writing out a color3 value, / by 255. For example:

..BackgroundColor3 = Color3.new(255,152,111)


turns to:

..BackgroundColor3 = Color3.new(255/255,152/255,111/255)


Hope this helps anyone!
