Difference between the measured and de-blended G – RP colours for the identified white dwarfs and their location on the CMD. For comparison, the 50 pc Gaia DR3 sample is shown in the background (grey points); only objects with BP – RP colours in the range 0.0 mag < BP – RP < 4.25 mag (the applicability range of the de-blending correction) are plotted. Left: CMD using the published G – RP colour. Right: CMD for the same sample, but using de-blended G – RP colour.
