Expected behaviour
When we upgraded to the High Chart 5.0.11 we have used the Boost module for rendering the large Heatmap chart. It should render the chart properly with the colors we provide.
Actual behaviour
The heatmap chart does not draw properly. It does not plot the expected colors on the chart. Added question for the same on the High chart forum https://forum.highcharts.com/highcharts-usage/canvas-solution-for-long-heatmap-chart-t38375/
Live demo with steps to reproduce

In the mentioned JSFiddle. We are seeing the issue that color plotted for the points are not correct.
If you mouse over on the blue point value is 70.13 and shows high lighting correctly on the legend but on chart it has plotted in blue color.
It looks like the plotting color for the point is wrong.
