Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
Having values of different types in a single collection is a bad practice.
Add some smaller samples (e.g. 1x5), especially for the edge cases where brightness levels change
Define in the description how to calculate brightness from RGB
re-raising as an issue
Some details are missing.
For example, how does this kata define brightness? There are at least 4 ways to do that here: https://en.wikipedia.org/wiki/HSL_and_HSV#Lightness
Why publish the same kata when the old one has been retired?
Duplicate to all shape formation katas ~~
Fixed python snake_case
In regard to this kata being a duplicate I have looked for any kata similar to this and I haven't found
any so if you find one please let me know
In python, function name and parameter should use
snake_caseduplicate of all drawing and shape-building katas
FYI - Take care not to end up duplicating this Kata...
