Thank you for concisely summing up my entire issue with the “Teal” debate.
By the same metric that “Earth Blue” isn’t “Dark Blue-Green” because there is not enough “green”, “Bright Bluish Green” isn’t “Dark Blue-Green” because there is not enough “dark”.
(I know that was confusing, you can read it a few times over because it does actually make sense. )
When Greg described Lariska’s colour, you can be pretty confident that he wasn’t talking about a specific Lego part colour. The issue here is that the colour he described doesn’t even come close to any colours Lego actually makes.
That’s why, I feel the “Teal” rule should be more relaxed for Lariska than Artakha’s “Sand Green” rule, because there’s not really an appropriate specific shade for the actual colour.
(And I also agree that on a colour spectrum, “Earth Blue” or even “Earth Green” are way closer to the colour in question than “Bright Bluish Green”, so that needs to be considered.)
tl;dr: Calm_Hawk is dead right, you should listen to them.
