You can make Palestine turn green once guessed, if you want. Just write "ps" in the Hint column for Palestine. And in the description, put the following code (without the spaces, obviously)
Please read the instructions! You are correct in saying that Sint Maarten, Curaçao and Aruba are part of the Kingdom of the Netherlands, but you omit to mention that they are not a part of the country of the Netherlands. Countries 197 to 205 are (as is stated in that quiz's instructions) countries that have self-proclaimed country status plus mass recognition by other countries AND/OR clear independence in their self-administration from any associated countries.
There's a little error in the quiz. If you type "Gre", it will highlight both Greenland AND Denmark, which I don't know if is intended.
I realized this because I had one country missing in Europe but the whole continent was green. Without looking at the alphabetical order it would've been impossible to realize.
Collaborate the quiz with me (Collaborate button is in step 1, under Quiz Options) and I will fix it for you. I'll write a reply to this comment when you can resubmit.

Same for Niue and Cook Islands in New Zealand
