Light or Dark Mode Tutorial - Luminance Detection

As a colorblind trader, I think accessibility is a big deal. This script auto detects the chart background color and optimizes text color based on luminance.

Luminance detection is based on pine script new chart.bg_color feature, allowing lines, tables, etc to be optimized. Thanks to TV team for releasing this in the latest update/blog post today! This makes it simple to optimize scripts based off the knowledge that max luminance = 765 (rgb 255 + 255 + 255), thus we know that lum <= 383 is "dark mode" and lum > 383 is "light mode".

Try changing the chart background color and see how this script changes the table printed on the chart. I hope more script authors will begin to utilize this concept and that even better contrast detection may be built future pine script iterations.
