Better default palette?

I've finally found something that I think is pleasing to the eye:

columns: 19,
colors: ['ffebee','fce4ec','f3e5f5','ede7f6','e8eaf6','e3f2fd','e1f5fe','e0f7fa','e0f2f1','e8f5e9','f1f8e9','f9fbe7','fffde7','fff8e1','fff3e0','fbe9e7','efebe9','eceff1','ffffff','ffcdd2','f8bbd0','e1bee7','d1c4e9','c5cae9','bbdefb','b3e5fc','b2ebf2','b2dfdb','c8e6c9','dcedc8','f0f4c3','fff9c4','ffecb3','ffe0b2','ffccbc','d7ccc8','cfd8dc','f5f5f5','ef9a9a','f48fb1','ce93d8','b39ddb','9fa8da','90caf9','81d4fa','80deea','80cbc4','a5d6a7','c5e1a5','e6ee9c','fff59d','ffe082','ffcc80','ffab91','bcaaa4','b0bec5','e0e0e0','e57373','f06292','ba68c8','9575cd','7986cb','64b5f6','4fc3f7','4dd0e1','4db6ac','81c784','aed581','dce775','fff176','ffd54f','ffb74d','ff8a65','a1887f','90a4ae','bdbdbd','ef5350','ec407a','ab47bc','7e57c2','5c6bc0','42a5f5','29b6f6','26c6da','26a69a','66bb6a','9ccc65','d4e157','ffee58','ffca28','ffa726','ff7043','8d6e63','78909c','9e9e9e','f44336','e91e63','9c27b0','673ab7','3f51b5','2196f3','03a9f4','00bcd4','009688','4caf50','8bc34a','cddc39','ffeb3b','ffc107','ff9800','ff5722','795548','607d8b','757575','e53935','d81b60','8e24aa','5e35b1','3949ab','1e88e5','039be5','00acc1','00897b','43a047','7cb342','c0ca33','fdd835','ffb300','fb8c00','f4511e','6d4c41','546e7a','616161','d32f2f','c2185b','7b1fa2','512da8','303f9f','1976d2','0288d1','0097a7','00796b','388e3c','689f38','afb42b','fbc02d','ffa000','f57c00','e64a19','5d4037','455a64','424242','c62828','ad1457','6a1b9a','4527a0','283593','1565c0','0277bd','00838f','00695c','2e7d32','558b2f','9e9d24','f9a825','ff8f00','ef6c00','d84315','4e342e','37474f','212121','b71c1c','880e4f','4a148c','311b92','1a237e','0d47a1','01579b','006064','004d40','1b5e20','33691e','827717','f57f17','ff6f00','e65100','bf360c','3e2723','263238','000000']
