The Prophet ﷺ used to wear tanned leather sandals and dye his beard yellow with wars and saffron, and Ibn 'Umar used to do that too.  

أَنَّ النَّبِيَّ ﷺ كَانَ يَلْبَسُ النِّعَالَ السِّبْتِيَّةَ وَيُصَفِّرُ لِحْيَتَهُ بِالْوَرْسِ وَالزَّعْفَرَانِ وَكَانَ ابْنُ عُمَرَ يَفْعَلُ ذَلِكَ  

When a man who had dyed himself with henna passed by the Prophet ﷺ, he said: How fine this is! When another man who had dyed himself with henna and katam passed by, he said: This is better than that. Then another man who had dyed himself with yellow dye, passed by, he said: This is better than all that.  

مَرَّ عَلَى النَّبِيِّ ﷺ رَجُلٌ قَدْ خَضَبَ بِالْحِنَّاءِ فَقَالَ مَا أَحْسَنَ هَذَا قَالَ فَمَرَّ آخَرُ قَدْ خَضَبَ بِالْحِنَّاءِ وَالْكَتَمِ فَقَالَ هَذَا أَحْسَنُ مِنْ هَذَا قَالَ فَمَرَّ آخَرُ قَدْ خَضَبَ بِالصُّفْرَةِ فَقَالَ هَذَا أَحْسَنُ مِنْ هَذَا كُلِّهِ
