Whilst colour can be subjective, in this case it is clearly yellow and a mistake by the OP, because the preceding bar is clearly orange.
With a hue of 7˚[0] the middle color is in the middle of the red range[1], it's on the pink side of scarlet (8.5˚, 100%, 100%).
The rightmost bar has a hue of 47˚[2] making it an orange-yellow[3], calling it an orange (if a light one) is not insane.

I see red all around.
> Additionally the 'Analogous Colors' contains an even more obvious orange, and pink, but no sign of red.
Hue-wise, red is in the middle of orange and pink, if your analogous colors are orange and pink your base is a red. That's exactly what you get for scarlet: http://www.color-hex.com/color/ff2400 or pure straight no-frills red: http://www.color-hex.com/color/ff0000
I mean, obviously, the color is blue. Or is it gold? In any case, it's definitely a dress...
