uniform vec3 color;// = vec3(0.0)
uniform float colorPhase; // = 0.4 ; // if 0.0, there is no black phase, if 0.9, the black phase is very important

  return mix(
    mix(vec4(color, 1.0), getFromColor(uv), smoothstep(1.0-colorPhase, 0.0, progress)),
    mix(vec4(color, 1.0), getToColor(uv), smoothstep(    colorPhase, 1.0, progress)),
    progress);
