I am just playing around with plotting – hard to find something handy and well documented. There’s some documentation of plot.ly – but only for Javascript and I can’t figure out how that was ported to be used within Plots.jl

I would like to draw a surface with a single color (not completely opaque but I got that):

```
using Plots
plotly()
n = 180
u = linspace(0,2*π,n);
v = linspace(0,π,n);
x = cos.(u) * sin.(v)';
y = sin.(u) * sin.(v)';
z = ones(n) * cos.(v)';
surface(x,y,z,opacity=0.5)

```

And I found nothing how to set the surface color nor how a color is specified; a html string maybe? Is there some comprehensive documentation of all options of `surface`? I couldn’t find anything, though for example for scatter plots (I would like to impose one afterwards) theres `"color" => "rgb(127, 127, 127)"`- see [3d scatter plots in Julia](https://plot.ly/julia/3d-scatter-plots/) – but how to specify that for a surface? `surfacecolor` doesn’t seem to exist, `surface_color` neither, any Dict or String approach also failed.

Any examples/ideas how to set a surface color of say `(0,0,0.7)` (in [0,1]^3) ?

Just facing the same problem. I hope there are better solutions, but here is my workaround:

```julia
using Plots, Colors
plotly()
const_color = cgrad( [RGB{Float64}(0.5,1,0.5) for _ in 1:2] )
surface( x, y, z, color = const_color )

```
