# Module `Ot.Color_picker`

```ocaml
val make : 
  ?a:[< Html_types.div_attrib Class ] Eliom.Content.Html.attrib list ->
  ?hsv:(int * float * float) ->
  ?update:(int * float * float) React.E.t Eliom.Client_value.t ->
  unit ->
  [> `Div ] Eliom.Content.Html.D.elt
  * (int * float * float) Eliom.Shared.React.S.t
```
