Created attachment 32976 [details] patch with proposed changes Was previously missing. The implementation takes the alpha channel from the Java Color. This is probably less clutter than adding an additional setAlpha method. Added use to Tutorial3. NB: the alpha channel only works for setters, not getters.

Normal HSSF colours don't have an alpha channel. Extended HSSF colours do, as do non-theme XSSF colours If you haven't already, it might be worth you looking at how it works (or doesn't...) for SpreadSheet extended colours / xssf colours, then see if there are any ideas from there that can be used in the slideshow side / good ideas from the slideshow side which can go to spreadsheet

I'd guess the first step would be to at least commonalize some of the hslf/xslf colour handling.
