Hi!
My best guess of his colour description would be: Apricot mackerel tabby
This would be my best guess at a genetic breakdown for this kitty! I'm not sure how much you know about kitty genetics so I included some small explanations of what I chose and why

| XOY | - Genetically Male Orange based cat
| (B, b or b1) and (B, b or b1) | - Doesn't show any black or brown colours, so it might be anything
| d d || Dm and (Dm or dm) | - Together these would make a regular Ginger kitty into an Apricot kitty because he's a little lighter, but not like cream
| (A or a) and (A or a) | - Orange is special in cats, and even if they are genetically solid, the coat will still look tabby. If they're genetically solid this is called "pseudo-tabby". So he could be either of these
| Mc (Mc or mc) || sp sp || ta ta | - This group determine the type of tabby that the cat is
| ii || (WB, Wb or wb) and (WB, Wb or wb) | - This group determine if a cat is chinchilla or shaded, and golden or silver.
| C and (C, cb or cs) | - This chunk is responsible for and colourpoint colouring
| ww || ss | - This last chunk is for dominant white and white spotting so both of these are none
Also the white stripes aren't possible irl with simple genetics, so you could pretend he painted it on or something

I can also post the genetics I chose for him when I post the kittens, I'll be choosing the combination that'll give the most variety in kittens
