Colors in vvvv are represented by 4 color components in a range 0..1:

  • R for Red
  • G for Green
  • B for Blue
  • A for Alpha (defines transparency)

There is also another way to represent a color in RGB space, which is typically more intuitive to adjust:

  • HSL (Hue, Saturation, Lightness)
  • HSV (Hue, Saturation, Value) aka HSB.

The IOBox (Color) uses the HSV representation by default, see Color IOBoxes.

Note, other software packages can specify individual components in another ranges:

  • RGB: 0..255 for the Color channels and 0..100% for the Alpha
  • HSL: 0..360° for the Hue and 0..100% for the Saturation and Lightness.

Don't forget to convert the values to the 0..1 range.
There are convenient RGB (Color Join Picker), HSV (Color Join Picker)and AsColor (String Hex) for helping. Or just type the expression like 270/360 into the IOBox to convert 207° of Hue into 0..1 range.

When you need to save / load a color to a file or send / receive it over the network it has to be represented as a String or Raw data.

joreg: @herbst re install path please see this discussion: https://discourse.vvvv.org/t/installer-doesnt-ask-for-path/18234

herbst: Also, offline installer links greet me with a TeamCity login request. ("guest login" works, but that was just a lucky guess)

~5h ago

herbst: Why does the current installer neither let me choose nor tell me where vvvv gets installed to?
