No, They're basically sub species. Grey is Porteri, Red Rosea. But they're still the same species if that makes sense.
Color variations can occur in the same sac.
One of my females just molted. She was a darker brown color throughout. Now she looks like my other one, lots of grey and shiny pink carapace. The first 2 pictures are before and after of the same tarantula. The third is my other female. The second picture is poor quality but she looks just like the other one now. The before and after pictures are 9 months apart. The G rosea and G porteri confused me so I just call them rosea.
Yeah I wasn't sure if it was that dark brown its whole life until last molt or not. That one layed an egg sac the first week I got her... But lost them all. Seemed infertile due to her abandoning it. When she was dark brown she was a vicious T. Since molting its very calm, couldnt be bothered. And yes I love the grey with shiny pink, very pretty.
