Advertisement Are there any colours you wish were more prevalent in tarantulas? Do you look at all the swathes of browns and tans and think, man, I wish there was some more pizazz. It's amazing just how much entertainment you can get by simply changing the hue on tarantula pictures, and sometimes you get interesting results. I'm definitely not easily entertained. I recommend you try it if you're ever bored. I'd love for an iridiscent green tarantula myself, as it's my favourite colour. Think OBT but green all over, that kind of piercing green. I know that some Avicularia species are green but they're more muted and subtle, instead of eye-piercingly bright. I've also noticed red isn't very apparent either. It'd actually be interesting if there was some explanation as to why certain colours don't really appear on tarantulas. Most red colour forms are more orange or russet rather than crimson red to me. Theraphosinae sp. "Panama" is the only one that really screams 'red' in my head, though I think the black alongside it gives me connotations regarding magma and such. I know very little scientifically so, please educate me if you have any idea as to why their colours are as they are, and that's the reason we don't have rainbow coloured tarantulas wandering around.
