Median infrared residuals are shown as a function of the QSO reddening parameter, E(B − V)BBB. Black circles represent the median residual values for each E(B − V)BBB bin for all QSOs irrespective of colour classification. The error bars represent bootstrap 1-σ errors. The same relation is shown for the red and control QSOs as red and blue shaded areas, respectively. A clear trend can be observed, where the infrared residuals increase with larger reddening values for all samples.
