hi, we don't have colours (we only change them for holy week, Pascha and Christmas) but we do have environmental hymns... http://tasbeha.org/hymn_library/view/1277
You water its ridges abundantly, You settle its furrows; You make it soft with showers, You bless its growth. You crown the year with Your goodness, And Your paths drip with abundance.
فليروي حرثها ولتكثر أثمارها، وتفرح بقطراتها فتنبت، تبارك إكليل السنة بصلاحك، وبقاعك يمتلئ من الدسم.
this one is not a 'modern' hymn, as you can see!
we always celebrate this service, as the coptic church actually started re-numbering the years in 284AD in order to commemorate the vast number of martyrs who suffered that year. so this is a major service in our church, and we encourage you all to remember it too and to commemorate the church's saints and all the years of God's care for His church.
in our service, each church brings out the relics of the saints that it has and replaces the covering on their box with a special mixture of oil and spices that the priests mix freshly every year. this takes a big part of the service and then the readers process around with the icon boxes and we kiss them and thank God for the lives of the martyrs and saints and for His great grace and love to us all and for His care for the church both here and in heaven.
we also thank God for the new year and have many happy hymns of praise to Him.
if you don't have a priest for new year, you can still kiss all the relics and sing to God and pray.
i love new year!
