Nama : Tanggal : Produk : Daun Sereh Kering Penilaian untuk : Overall Warna Instruksi : Dihadapan Anda terdapat 3 sampel daun sereh kering. Anda diminta melakukan uji terhadap warna sampel. Pertama-tama letakan sampel ditempat yang dapat terlihat jelas. Kemudian secara berurutan, dari kiri ke kanan amati dan bandingkan warna sampel dan urutkan warna sampel dari yang paling anda sukai (beri nilai 3) hingga sampel yang paling tidak anda sukai (beri nilai 1) dengan mengisikan kode sampel sesuai dengan tingkat kesukaan Anda pada kolom dibawah ini. (Anda boleh mengulang sesering yang anda perlukan dan ranking Tidak Boleh Sama) Kode sampel
