This looks solid. Thank you for moving the tooltip meta field(s). Also thank you for a node tooltip.

I feel the tooltip timeout might be better suited to being adjustable. 500 feels too short (for me) and I like to use 750+ -- seems like an easy setting expose.

thank you for the update and changes!

I'm currently testing and I'm not seeing anything appear on any node. Even after restarting the browser (currently firefox) and making sure that the node I was testing was a newly created one.

class EmptyRGBImage:
    @classmethod
    def INPUT_TYPES(s):
        return {"required": { "width": ("INT", {"default": 1024, "min": 1, "max": 16384, "step": 1, "tooltip":"Test"}),
                              "height": ("INT", {"default": 1024, "min": 1, "max": 16384, "step": 1, "tooltip":"Test plop"}),
                              "batch_size": ("INT", {"default": 1, "min": 1, "max": 4096}),
                              "r": ("INT", {"default": 0, "min": 0, "max": 255, "step": 1, "tooltip":"Surely it must be about the red color."}),
                              "g": ("INT", {"default": 0, "min": 0, "max": 255, "step": 1, "tooltip":"A color related to something needing to be touched."}),
                              "b": ("INT", {"default": 0, "min": 0, "max": 255, "step": 1, "tooltip":"The sky, the sea and my heart when you're not here."}),
                              }}
    RETURN_TYPES = ("IMAGE",)
    FUNCTION = "generate"
    CATEGORY = "image"
    def generate(self, width, height, batch_size=1, r=0, g=0, b=0):
        r_normalized = torch.full([batch_size, height, width, 1], r / 255.0)
        g_normalized = torch.full([batch_size, height, width, 1], g / 255.0)
        b_normalized = torch.full([batch_size, height, width, 1], b / 255.0)
        return (torch.cat((r_normalized, g_normalized, b_normalized), dim=-1),)

Am I doing it wrong?
