  Mapping JSON data to colour ramp in AE

  Posted by Aoife Mccarthy on June 18, 2020 at 8:48 pm

  Me again! I’m trying to map values stored in a JSON file to a colour ramp in AE. Something like:

  linear(myData.value, 0, value_max, #FFFFFF, #000081)

  …in the fill colour property, if the linear expression could be used in this way. So taking a value from my dataset, figuring out where it sits along the colour gradient and applying that fill colour to the shape.

  Can anybody help?

  Just as a test, you could play around with this, to see if it’s close to what you want:

  s = effect(“Slider Control”)(“Slider”);
  c1 = hexToRgb(“FFFFFFFF”);
  c2 = hexToRgb(“000081FF”);
  linear(s,0,100,c1,c2)
