Opacity/alpha channel on text, how?

When you define a color using RGB you could attach an alpha channel to add transparency. My question is how to achieve this on text when using the "|c" formatting option?

If I would set the color of an entire label to red I could do like this:

Code:

myLabel:SetColor(255, 0, 0) -- equivivalent of hex code FF0000

Or I could do like this:

Code:

myLabel:SetText("|cFF0000" .. myText .. "|r")

If I would like the red text to be semi-transparent I could do like this according to the method in the first example:

Code:

myLabel:SetColor(255, 0, 0, 0.5) -- equivivalent of hex code FF0000 with 50% transparency

But how do I achieve this using the "|c" method? I would like to do anything similar to:

Code:

myLabel:SetText("|cFF00007F" .. myText .. "|r")

Or:

Code:

myLabel:SetText("|cFF0000|7F" .. myText .. "|r")

But neither alternatives works. Could anyone shine some light on this issue?

Controls have an additional method SetAlpha(a). Note that values for SetAlpha as well as SetColor should be in the range <0; 1>.

AFAIK color code can't have transparency. All you can do is as merlight suggested use myLabel:SetAlpha(0.5).

As for the hexadecimal color code - default ZO_ColorDef object works with ARGB, i.e.:
7FFF0000

Lua Code:

local myColor = ZO_ColorDef:New("7FFF0000")
 
myText = myColor:Colorize("Hello World!")
myLabel:SetColor(myColor:UnpackRGBA())

But still as I said above, transparency in the color code will be ignored, value of myText will be "|cFF0000Hello World!|r".

Thanks both of you! I was worried it wasn't possible to set alpha on just a part of the text, however I was hoping to be wrong so I didn't have to split ut my control into multiple labels. Well, not much todo until the game supports it (wink wink ZO).
