+/* Heatmap Colors The heatmap real-time graph uses color blending to choose the color for which to render each bucket. Basic d3 categorical colors do not work well in this instance because the colors in the sequence vary wildly in precieved luminosity. Below we define small subsets that should work well together because they are of similar luminosities. Note: darker colors work better since we use opacity to denote "height" or "intensity" for each bucket after picking a mix color. */
