Tryed a mix of:

#[derive(Apiv2Schema, Debug, Deserialize, Serialize)]
#[openapi(minimum=0, maximum=255)]
pub struct ApiNeopixel {
    #[openapi(minimum=0, maximum=255)]
    red: u8,
    green: u8,
    blue: u8,
}

no success yet:

Maybe we can integrate with validator:

#[derive(Apiv2Schema, Debug, Deserialize, Serialize, Validate)]
pub struct ApiNeopixel {
    #[validate(range(min = 0, max = 255))]
    red: u8,
    #[validate(range(min = 0, max = 255))]
    green: u8,
    #[validate(range(min = 0, max = 255))]
    blue: u8,
}

Yeah a validator like that seems like a good idea.
Although in general we could also improve things, as with u8 the min and max should also be set?

I think it could be an optional field, if not set - It will take the minumum and maximum values from integer type.
But if defined you can set your own limits.

Sorry about the long delay in addressing this..
With this I think the min/max are addressed for both your issues, please let me know otherwise.
