OpenAI's new image generation model is autoregressive, while DALL-E was diffusion. The yellowish tone is an artefact of their autoregressive pipeline, if I recall correctly.
Most DALL-E 3 images have a orange-blue cast, which is absolutely not an unintended artifact. You'd literally have to be blind to miss it, or at least color-blind. That wasn't true at first -- check the original paper, and try the same prompts! It was something they started doing not long after release, and it's hardly a stretch to imagine why.
They will be doing the same thing for the same reasons today, assuming it doesn't just happen as a side effect.
