Start as always with an underpainting of yellow and white and then block in some sky with cobalt and white.
Loosely stain in the darks and lights to the background trees with a paper towel. The darks are cobalt and sap green with some white and for the lights use cad yellow light and white.
On the right side the trees have more darks and shadowed areas so you can use the full strength of cobalt and sap without the white for these areas. You can also add in some purple a desired. Next begin the next layer which is done also with a paper towel but this time with a tapping technique. Use the tapping technique repeatedly to allow for some blending but do not over tap or it will be too much and you will have muddling. The colors are the bright yellow/green using white and cad yellow light. You can also add some midtone greens with the tapping technique. Continue this through the tree areas but fade out as you come closer to the area where the focal flower will be. We do not want too much busyness to be in this area.
Here is a close up of the upper left had corner to see the paper towel tapping technique.
Here is a full view of the background completed. Taper the paper towel technique towards the center and bottom of the background to be less stokes to none.
Now use paper towel in upward stroke motion and create a field of greens using shorter strokes in the background and gradually enlarging the strokes as you come forward. This creates distance. Start with white and sap, a very pale pastel lime color. Then add yellow and white for the next color mix using the same strokes. Next add in the purple flowers keeping everything a bit blurred. The purple flowers mix is cobalt, very little purple and white.
Next add in rose and white for the next set of flowers. Keep them somewhat blurred as well. Use a paper towel to add the flowers or if you feel more comfortable use a small angled paint brush.
Continue adding in flowers both the purple and the rose softly. Also add in some darker stems with a sap and cobalt and white mix to show some shadows in the green stems at the bottom. Be sure to overlap the flowers onto the dark part of the background so the flowers pop against the contrast.
Lay in the stems to the purple flowers with a light color- white and yellow.
Add a dark to the stem and blend from one side of the stem across to the other side of the stem. This creates a roundness. Next add stems with buds. Use a yellow for the light and green with cobalt for the dark. Blend paint after laid on the canvas.
Using cobalt and purple, add in the sprout of the flower. Use white and the blue mixture for a highlight. Remember to always break down a color with 3 values, light; midtone; dark. In this case you can just use the light and the dark and blend them as needed right on the canvas to get the middtone.
Continue adding buds and flowers.
Continue to build the stems and the buds.
Full view of purple flowers complete.
Start by adding a midtone and stroke the spokes from the center outward. Make the spokes on the bottom shorter since these come forward. Use rose and white.
Next add dark spokes having them mostly at the bottom. Use rose and cobalt blue.
Now add the buds in a midtone or light depending on where the light falls on the flower. Then add the light and dark to the buds. Use rose and white for light and rose and cobalt for dark.
Here we are addding the opened flowers of the larger flower. They appear to look like stars. Some are opened fully and some are opened partially. The partial ones are more on the edges. The stars are in the front. Some stars are flat and some are bent to show how it sits on the “sphere” of the flower. And some are hinted in between buds and spokes. Use the lightest color of rose and white, and then a dark to accompany it.
