Why is my color with Alpha washed out in XOJO

Getting Started
1

I have a textarea which presents a couple of colors with alpha and both are washed out.
This is the code for the red background below

CWrngColr = Color.RGBA(255, 000, 000, 208) or &cff0000d0

I also use a canvas with a png backdrop of the SAME color.
This is the image of the png.

They are significantly different. Why?

Do you want solid red?
If so, why use an alpha?

CWrngColr = &CFF0000

If you have a colour with transparency (208 in your case) the colour that was there before will have an effect on your red, in your case a white was in the background first so the red will be slightly mixed with white, thus making the pink you see. If you had the colour on a black background, the red would look darker.

Thanks. Julian. My confusion comes from the image below which has transparency in it. I like the translucent and will probably use that instead. I do not remember a setting for getting an image with translucent

Oh. I had the values for the alpha backwards.
