Did you ever find a fix for this? I need to make the alpha 0.44, but I can't figure out how to.

The reason is the alpha of fallback UIColor returned by colorFromHex is fixed at 1 https://github.com/atomikpanda/libcolorpicker/blob/3ff8e63e773fa251a4b4bc2b6cbf560661137209/libcolorpicker.mm#L125-L128 A workaround is to manually set default value like this 

NSString *colorString = prefs?(prefs[@"bgColor"]?:@"#0027FF:0.2"):@"#0027FF:0.2"; 
UIColor *bgColor = LCPParseColorString(colorString, nil);
