Cool, but... Is this just a picture with different filters, or is there code somewhere?

Also, wouldn't the goal be for your heaviest consumers to be aware of the office of electricity and model their start/stop around that?

As opposed a human having to see the color of a bulb (which will be the same color at each point every day) and having to do it all manually?

What’s the difference between this and using a time of use plan and having the light adjust based upon time of day? Is there a significant difference in cost savings to warrant the extra programming? How frequent does the light change color and what thresholds do you have for them being cheap, natural, and expensive? Great idea! Im genuinely curious!

First of all, it's fun to play with this, even when there is no significant benefit.
Second, there are significant differences sometimes. The hourly price depends on supply and demand - factory consumption, weather (wind/water), power plant maintenance, etc.

Although usually "day expensive, night cheap" is good enough, there are peaks. Sometimes during the daytime, the price can be negative, or it can be 60 cents/kWh. At those times you might want to avoid using sauna for example.
You can see the prices here: https://www.nordpoolgroup.com/en/Market-data1/Dayahead/Area-Prices/ALL1/Hourly/?view=chart

Personally, my subscription is a hybrid. It's a fixed fee ± difference of the current price to the rolling average. So I actually calculate the average to the current price with a tolerance of ± 5 cents. In the chart below you can see the red line, which is the trigger for the red light (11.16). Green would trigger at 1.16. The yellow line at the bottom is the average, at 6.16.
