ग्रहचारः केतवश्च
धूम्रैर्नृपपिशंगैस्तु जलदाधोमुखैर्जगत् ।शुभोऽर्कः शिशिरे ताम्रः कुंकुमाभा वसंतिके ॥ ८ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 8.
With smoky rays, there is a risk to the king. With tawny rays, the Sun brings rain. With rays facing down, the world may suffer harm. The Sun is good if copper-coloured in late winter, and saffron-coloured in spring.
Simple meaning: Smoky rays may harm the king, downward rays the world. Tawny rays bring rain. A copper late-winter Sun is good.
ग्रीष्मश्चापांडुरश्चैव विचित्रो जलदागमे ।
The Sun has a set colour in each season, such as many colours in the rains.
पीतः शीते सिते वृष्टौ ग्रीष्मे लोहितभा रविः ।
A yellow, white or red Sun in these seasons can bring illness, drought and fear in that order.
इन्द्रचापार्द्धमूर्तिस्तु भानुर्भूपविरोधकृत् ।
A half-rainbow Sun brings strife among kings. A hare-blood-red Sun means a battle soon.
