Fixed the order of arguments for the PHP tests here

C#: method name should be PascalCase (Please refer to implementation of backward compatibility here )

• No random tests in JS

• Node 18 (mocha + chai) should be enabled (Refer this and this for more info)

• Python new test framework should be used (Refer this & this for more detail)

• Ruby 3.0 should be enabled (Refer this & this for more detail)

Needs a static test with similar but different colours, such as "brown" and "blue".

Also, random tests. But that's been raised already.

Your Kata needs more extensive test coverage to prevent easy cheap-cheat solutions and/or logically flawed solutions. The most common way to increase test coverage is through the inclusion of randomly generated test cases at runtime so please add these. The lack of test coverage in a Kata as an Issue is recognised as an official CW stance.

Nice kata. But needs some random tests ;-)
