Can you please help me? I have this:
local mycolor = 0x0000ff

how can I put it in a string without it being converted to 255? I would like to get 0x0000ff or at least 0000ff. I tried:

print(tostring(mycolor)) -- 255
print(mycolor) -- 255
print(string.format("%q", mycolor)) -- "255"

Thank you.

    print( ("0x%06x"):format(math.random(0xffffff)) )
    or
    print( ("%x"):format(math.random(0xffffff)) )

    this kind of notation is scifi for me, so perhaps you might also prefer:
    string.format("%x",0xffffff)
    which is the same but written differently.

    :D
    It basically means this:
    local myString = "0x%06x" -- means print "0x" as regular string, then add converted hex number with 6 leading zeros
    -- so if you call "print(("%x"):format(0x0000ff))" then you will get just "ff", but with "%06x" result is "0000ff"
    print(myString:format(0x0000ff))
    -- or
    print(string.format(myString, 0x0000ff))

    And if you want to write a string as its hex representation:
    local s="Hello"
    print(("%02X"):rep(#s):format(s:byte(1,#s)))
