[interface] Overlay for slowed down units

[Caphriel]

Feedback from a red-green color-impaired person:

• tinttest1.png: Usable with difficulty. Slowed and slowed+poisoned are confusable, poisoned and slowed+poisoned are confusable.
• tinttest2.png: Usable with difficulty. Poisoned and slowed+poisoned are confusable.
• tinttest3.png: Usable. Slowed+poisoned and normal may be confusable, but probably not.
• tinttest4.png: Usable. Slowed+poisoned and normal are confusable.
• tinttest5.png: Unusable. Slowed and slowed+poisoned are confusable, and slowed and normal are confusable.
• tinttest6.png: Unusable. All three status conditions are indistinguishable.
• tinttest7.png: Unusable. Slowed and slowed+poisoned are indistinguishable, and both are very similar to plain poisoned. (Sorry, Gambit )
• tinttest8.png: Unusable. Slowed and slowed+poisoned are indistinguishable, and both are very similar to plain poisoned, but worse than 7.
• tinttest9.png: Usable. No confusion.
• tinttest10.png: Unusable. All three status conditions are indistinguishable.

As a side note, the HI seems to be a bit more blue than most units in the game, which is what lead to the similarity between the normal one and the poisoned+slowed one in the blue tints.

Thank you! This is exactly what I need.

So it's really between 3 and 9 right now.

On 9, the brightness of the three affected units is closer to equal. On 3, slowed looks somewhat brighter, and thus slightly out-of-place. For that reason I'd vote for 9. As that's the one already in the game, I'd say good pick!

I think 3 matches the intensity of poison much closer (without it being overboard like 4). 9 is useable, but 3 pops more so it's much easier to tell the difference between slow and poison+slow and just visually reads better. So my vote is for 3 if that matters.

Playing IFtU in 1.9.10- enemies were getting slowed but it seemed as though there was no color change- the units are already a blue-ish grey color. I recall reading in the changelog that the slow color was in the game now? If so, I didn't notice. It may be a better idea to use a less subtle color to indicate it, like a cyan or yellow- but, mixing these with a green will only make a slight change, perhaps red is slow, green is poison, orange is both... Since a unit can be both slowed and poisoned an icon, eg the snail, would be more readable.
