What's wrong with this?

I haven't fiddled with Data Store that much and I'm terrible at anything to do with BrickColors but I'm still pretty unsure why this is broken The main parts of the script are:

doba = script.Parent.Parent.Parent
script.Parent.Parent.Parent:WaitForDataReady()
ds = game:GetService("DataStoreService"):GetGlobalDataStore()

color = ds:GetAsync(player.userId .."currentpants") or nil -- problem occurs around here
if color == nil then
    ds:SetAsync(player.userId .."currentpants",tostring(script.Parent.Parent.Parent.stats.lleg.Value))
    color = tostring(script.Parent.Parent.Parent.stats.lleg.Value) -- should be bright blue
end
script.Parent.Parent.Parent.stats.lleg.Value = BrickColor.new(color)
script.Parent.Parent.Parent.stats.rleg.Value = BrickColor.new(color)

rleg & lleg are BrickColorValues

Any solutions?

EDIT: changed

color = ds:GetAsync(player.userId .."currentpants")
 --to
color = ds:GetAsync(player.userId .."currentpants") or nil

still broken!
