Hi Tim,
I Checked out the Compose and Gadfly, and set transparent color works in
```
theme(default_color=RGBA(1.0,0.0,0.0,0.3))
```
but stack overflowed when set transparent color in
```
Guide.manual_color_key("legend",["label"],[RGBA(1.0,0.0,0.0,0.3)]), and
Scale.color_discrete_manual(RGBA(1.0,0.0,0.0,0.3))
```
stack overflow
