I still not received dark blue leather sample yet. Please let me know if there is any change. For bright red colour and grey colour leather sample, our team reviewed and selected it already. Not all of them is acceptable, but more than 3 range colours are selected. I hope that it would be useful for you. Refer to the chart you sent us, I am not sure that you have prepared same chart and kept at your side or not. If you do not have same chart you sent me, please let me know. I will cut the select one it in to 2 parts and make chart to you.
