blend-alpha

I can't figure out why points with gl_FragColor = vec4(255, 255, 255, .1); get darker and then lighter when overlaid with increasing density.

I'm using these blending settings:

blend: {
  enable: true,
  func: {
    srcRGB: 'src alpha',
    srcAlpha: 1,
    dstRGB: 'one minus src alpha',
    dstAlpha: 1
  },
  equation: {
    rgb: 'add',
    alpha: 'add'
  },
  color: [0, 0, 0, 0]
},

Tweaking them hasn't fixed the problem, but I'm not sure what I'm doing...
