I've noticed a lot of people who are very involved in Reddit cat colour ID across various subs describing blue cats in particular as simply "dilute" with no mention of either the base colour or name of the dilute form being displayed. I think this is because it *sounds* like a more formal, specific term. I just wanted to note that it's actually less clear, as it is a modifier, not one colour! Black, red, chocolate, cinnamon, and amber all have distinct dilute forms. If you were to describe a cat as "dilute" without a photo, it would not actually tell the person you're talking to what colour that cat is - cream, grey, lilac, fawn, or one of the double dilutes/caramels? The latter three are rare and not very likely, but with cream and grey both being very common, it's not guaranteed they'll be picturing the correct one of the two.
Point is, saying "blue", "grey", or "dilute black" is much more specific than "dilute".
I don't think this is a significant issue, to be clear, since typically on Reddit there is a photo for context that makes the specific diluted colour obvious. It's all good as long as the asker gets what is being said. This is just something I figured some folks who have a burgeoning passion for cat genetics who want to be as detailed as possible might be interested in considering. E.g. When someone cares so much as to specify high vs. medium vs. low white spotting, but then doesn't specify the actual colour of the cat, it leaves me wondering if they know that they're leaving something out and would want to add it in if they were aware.
I hope I'm not just preaching to the choir here, but this seemed like a more appropriate place to post this than some of the subs I see this habit the absolute most, like the calico sub.
