Cool colours - Lillejordveien, Skjomen

Am keen on cloud types but am struggling to identify these in the distance, would like to guess at cirrostratus due to the seeming high altitude but am not sure, they could be a form altostratus bunched together - it's typically altostratus that can give off a fine array of colour when the sun sets. Am prepared to be corrected if any wise Blippers happen to know for sure...
