Just go on as usual, you cannot tell anything by looking at the color at this stage.
Did you wash the DCM layer with water and brine as in the Buffered Performic Oxidation (https://www.thevespiary.org/rhodium/Rhodium/chemistry/peracid.html#performic3)

If you didn't, heating the product without washing away residual formic acid first is likely the culprit.
Also, don't start a new thread each and every time you reach another step in this procedure, continue in any of the other ones you have already started.
