I then took the recurring hues of pink, purple, green, blue and orange and made swatches from them using ColourSchemeDesigner.com (another 'Phil-suggested' site), so that I could later incorporate them in my images.
The first three colour palettes are tetradic colour schemes, the fourth is triadic and the fifth is complimentary.
The colours are very vibrant, which reflects my own personal preference and style of using bold colours in contrast with dark, black tonal work to develop somewhat of a visual harmony. This is a very 'comic book' approach, and is probably the most familiar to myself, but it may not be suitable for concept paintings.
This is where I need some help. Do I sacrifice personal style choices in order to create, what I feel may be a slightly more generic, less interesting image, or do I work in a more comfortable way, developing the image how I envision it in my head with my own stylistic preferences, but risk coming out with (in the words of 'Photoshop' Phil) a more 'childish' image?
Please, give me advice! I'm a little stuck here! Thank you!
