Yellows — Raw Sienna, Koman and Yellow Ochre, Dark Brown- 
pink, and Gamboge, 
Blue — Indigo. 
Byrnes-brown, No. 1, is a useful colour for dark touches, it being 
clear and gummy. It may be had at Smith and Co.'s, Colourmen, 
Piccadilly, where I generally purchase my colours. 
Tor waterfalls, keep to grey in your forms and light and shade, 
slightly tinting over it the reflected colours. For Grey, use Indian 
Eed and Indigo. In old houses, &c, add Burnt Sienna to your 
Grey, Dark Brown-pink, Eaw Sienna, &c, varying them according 
to your feeling and the knowledge of local tints. In my fore- 
grounds and nearer parts of buildings I sometimes run into dark 
grey, yellows, and browns, so as to render the effect of no colour, 
and though it may sometimes appear dingy, touches of transparent 
colour, such as the raw Sienna, Byrnes Brown, &c, will clear out 
your effect. 
Permit me to add the best method I know of acquiring colouring 
is, by using your colours in sketching from nature with freedom ; 
copy what you see, not too minutely, nor slovenly ; when your 
time will allow it, try this method, and do not attempt much finish- 
ing till you have washed in the general features and character of 
your subject. 
I am almost ashamed to send you such a hasty letter. Tis 
very unconnected, and will, I fear, be but of little value. Time 
tyrannizes over me, or I would have endeavoured to arrange these 
thoughts in a more simple form. 
I am obliged to you for having so politely mentioned me to Mr. 
Smith, at Dulwich. 
I hope you will do me the favour not to think of anything like 
a remittance, as indeed this has not been any hindrance, nor has it 
cost me any trouble. 
I shall rely on your having the goodness to excuse the running 
haste of my pen. Yours faithfully. 
Samuel Prout.
