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: Two #vvvv workshops this week in #berlin: Friday: Physical Computing, Saturday: Computer Vision. Tickets: upcoming-full-day-vvvv-gamma-workshops-in-berlin

joreg: @cznickesz also feel free to join our chat for such questions: chat

~5d ago

cznickesz: @joreg: Yeah, I´ll give it a try! Thx

~5d ago

joreg: @cznickesz: we're hoping this week. but depends on feedback. please test your project and let us know if it works.

cznickesz: @joreg: I should stop asking my questions so cryptic ;-) So right away: is final Beta39 hours, days or weeks away?

~5d ago

joreg: @cznickesz: the idea of an RC is exactly to make sure your projects will work with it. your last chance to report problems with b39.

~5d ago

cznickesz: So how "RC" is the "RC3"? I have to update an old project soon and I´m wondering if I should wait and directly update to Beta39
