Beautifully circuit?

Yes, very nice. Make the 555 timing resistors 10times bigger and to keep the timing the capacitor 10times smaller. Great to see you have used for the LEDs an extra resistor each, which you have to adapt for every color. Cuz different colors means different threshold voltages. Great! 👍

The circuit currently operates at 155hz, if it was to be built, the leds would appear to be on all the time. Also the 555 manufacturers recommend that the timing resistors be 1k or greater. Increasing the resistors and decreasing the capacitors as hurz recommends will overcome these problems, my favourite sizes are shown; http://everycircuit.com/circuit/5671739871461376

my favourite is highohmic as possible. As possible means to not make the cap tooooo small, keep it in nano range, check this with the background of power comsumption equal frequency and pulse pause ratio, but much lower current! http://everycircuit.com/circuit/5800115437305856

@hurz, definitely would improve the battery life.
