Exercise 3 Broken or Tertiary colours

Scale between orange red and a green blue. I mixed the green blue first to obtain the same tonal value as the orange red. I didn't need much blue as was very strong and a lot of white to maintain the tone, even though had been pre mixed with white. This also occurred in previous exercises at the end of Exercise 2.
Orang to violet: as the tones began leaning more towards violet again had to add further whit to maintain tone with orange and increasing proportion of violet to change the hue adequately when moving from lighter to darker tone such as this one, or from white or yellow.
From about 4 to 7 were murkiest (muted) colours ranging from grey brown to grey green . There is also a murky grey brown at no.4.
